Thank you you’re a great student that’s why you could make it at first attempt brilliant
Negative experience: Had a few lessons with him and he said that he would take me through the test. He then texted me at 2:30am to confirm a lesson with me for the following morning and expected me to be ready for the lesson which was not fully confirmed. This also meant that he had inadequate rest to pay full attention if our lesson went ahead. I then sent him a follow up message and he ignored me for a full week, then called to say that I'm ending terms with you in a very unprofessional manner. Methods were not very professional and would not recommend to anyone.
Fantastic experience: The best instructor ever! Amazing teaching, very patient and informative, thanks to him I managed to pass my driving test first time around a month later after meeting him!

Fantastic experience: Thankyou soo much for learning me the simplest way to be friendly with the car & the road so i can pass my test with first try. ‘Driving Genius’ Yes i may say you are Genius in teaching how to drive. Thankfully, Sushil Maharjan.
Fantastic experience: Absolutely fantastic experience with Nav! He not only helped me pass my driving test but also supported me in overcoming my driving fears. His patience, expertise, and encouragement made all the difference. Very friendly and easy to get along with making lessons that much better! I couldn't have asked for a better instructor. Highly recommend! ⭐⭐⭐⭐⭐
Fantastic experience: I genuinely believe that I could not have passed the driving test without Nav’s dedication and quality of teaching. Each lesson was structured and tailored to meet my individual need. Nav is patient and very observant. If there is a particular manoeuvre, route or skill that he feels that you are struggling with he will ensure that it is practiced fully and as many times as possible until you feel confident. I found that the mock tests in particular were the best preparation for the test day itself. All the 5 star reviews are credit to the great teacher that Nav is!
Thank you good appreciate your honesty
Fantastic experience: Navar is a very experienced instructor that guides you through the whole process with those finer details and tips that really boost confidence through the test.
Fantastic experience: Navar is a very good instructor, personable, punctual and to the point. He takes good care of the nervousness while driving.
Fantastic experience: Great experience, great instructor, Nav explains very well, he has patience and makes sure you get everything right. I’m glad he was my instructor.

Nav is an expert instructor who knows how to teach you the skills you need to be a safe and confident driver. His driving techniques are excellent and he is always patient, kind, and supportive. Nav is also very punctual and efficient, which made scheduling my practice lessons a breeze. He is a true professional who cares deeply about his students and their success, and I can't thank him enough for helping me pass my driving exam with confidence. If you're looking for a top-notch driving instructor, look no further than Nav. You won't be disappointed!"
Fantastic experience: Nav is a great instructor. He explains everything thoroughly and is extremely patient. Would definitely recommend him to anyone.

Fantastic experience: Started with nav 3 weeks before my test and I now passed first time. He’s very good and helped me prepare for test
Fantastic experience: Navar is a really good instructor, teacher more over a good brother. He is patient and professional. I took my driving lessons and skill test with him, really he boosted my confidence well. Moulding me perfect! Today my practical exam in Pinner went really well and I passed today! The course you take with Navar, will last a lifetime!!!
Fantastic experience: Passed my driving test first time with Nav in pinner after Learning with him for 4 weeks. Taught me everything I needed to do to pass my practical driving test always very kind, calm and punctual with well structured lessons. Plenty of mock tests manoeuvre practice well recommended instructor.
Fantastic experience: My wife didn’t have any confidence on the road when she started driving, but Nav (Drive Genius) gave her the confidence to drive and pass her tests. Now she drives us everywhere.
Negative experience: This instructor is very unprofessional ! I don't know how he got passed to teach others. He is very rude , always on the phone and not teaching properly. He is a con ! Please avoid and do not bother learning from him . He always cancels and reschedule and has no manners. As an individual suffering anxiety and trying to learn my driving he makes me panic more and brings my anxiety levels higher. He is being reported to Dvla and I 100% recommend you not to use him !
Negative experience: AVOID AVOID AVOID!! Very rude driver
Negative experience: Please, please, please avoid this driving instructor at all costs!! Nav is one of the worst driving instructors I have ever encountered. He is outright rude and unprofessional. He would shout at me for making the simplest mistake. I only had three lessons with him, but going to his lessons always made me super nervous because of how rude he is! He also cancelled two lessons of mine and moved my 2:30 pm lesson to 5 pm. He also talks badly about his other students, and he is very misogynistic and racist. Finally, Nav would sometimes be on his phone whilst I was driving (waste of money!!!!!!!)
Fantastic experience: Mr Navar is an amazing driving instructor. I called him after a friend recommended him to me. He is very punctual and he is very flexible. Which was amazing with the time schedule I had. Within about few weeks he taught me how to drive safely and efficiently. Massive thanks to Mr Navar because I passed the driving test first attempt with one minor. And he went all the way to Borehamwood for my test because I booked my test there. I was so nervous on my test day and Mr Navar helped me to clam down and made sure I do all my manoeuvres and remember all my show me tell me questions before the test. He went above and beyond to help me.. So I highly recommend him to anyone. And thank you so much mr Navar
Negative experience: Called to enquire about driving lessons. Had all sorts of unnecessary questions. First my partner enquired and he said he was available from as early as next week but when I called, he sounded uninterested and demotivated. Very demoralising, rude person.
Fantastic experience: Nav is one of then best people I’ve met, all lesson from my first were beneficial, he made every lesson feel easy and him being my instructor made me feel safe and learned so much. I passed my driving test time due to nav being the best
Thank you for your review. Much appreciated.
Negative experience: Leaving a 1 star review even though I didn’t get driving lessons with him. I messaged him about scheduling lessons and he was initially accommodating until the day of my supposed lesson. I was getting myself and my kids ready for the day, hence didn’t get time to respond to his text message and call at 08:20 for our arranged first lesson at 09:00. He accused me of sleeping in because I couldn’t answer his call; therefore cancelling my booking the last minute. I only got to see his message/call 10 minutes before the agreed time, when I was already waiting for him to pick me up. This is not a case of “customer is always right” but how businesses should not treat potential customers. In any line of business, there should always be respect and professionalism and clearly this person didn’t have one. I would have been a good student and would have probably given Nadar a good rating like other people here. But he was rude and that just doesn’t fly with me.
Fantastic experience: Great instructor, specialized in Pinner test areas. Friendly and patient, Highly recommend.
Fantastic experience: Thanks to Nav I have passed in my first attempt. I would definitely recommend him. He makes you familiar with all the test routes which is really helpful. His way of teaching manoeuvre are really good and the tips to make it perfect is excellent. He never loses his patience how many ever times you do it wrong. He is very friendly and approachable. Overall was a very good experience learning to drive with Nav. Thank you for all the support.
Fantastic experience: I passed first time, all thanks to my amazing instructor Navar. He is very calm and takes his time to teach you properly, ensuring nothing but success. I am very happy to have used driving genius to learn my driving. 100% recommend.
Fantastic experience: Nav is an outstanding driving instructor. His delivery of instructions are very clear. His tips and techniques on all the manoeuvres are perfect. Printed copy of showmetellme questions given early on. Very patient and understanding. Gives constructive feedback which helped me improve and understand my mistakes. Managed to calm my nerves and boost my confidence. Also his punctuality is spot on. All the mock tests were very helpful and he will make sure the lesson time is not wasted. If you have any doubts & questions, he will make sure they are answered quickly & effectively. Highly recommend to anyone who wants to pass first time.
Fantastic experience: Nav is an excellent and effective driving instructor, and helped me pass my driving test. I had previous driving experience, but still had a lot to learn and unlearn. Nav customised the driving lessons to fit my needs and identified and focused on areas where I needed to improve. Nav's teaching method is effective. Nav explains concepts related to a topic and then makes the student practice them. Nav also provides consistent and honest feedback which helped me fix some holes in my driving technique. The mock driving tests also helped me a lot. I felt fully prepared during my driving test as I had gone through similar scenarios during my mock tests.
Thank you Anurag you are a messing learner
Fantastic experience: I just passed my driving test because of my amazing driving instructor Nav. Not only did he helped me with my driving, but he boosted my confidence and to be more patience. That’s two life lessons that I’m so proud to gain. This is my second time doing my driving test and my first time with him. The different driving techniques that I have learned because of his hard work and myself also. We did it ! I definitely recommend him
Negative experience: Unprofessional. Turned up at the address with no warning or planned lesson and was rude
Negative experience: Totally inappropriate and unprofessional. He turned up, with no notice, at my house on a Sunday evening and then cancelled my lesson which was booked for the next day. He disturbed my landlord, my housemate, and myself sleeping after long shifts. I can totally see him wanting payment in advance (as he said he has had someone not pay him before) but this should have been requested. But, turning up unannounced was not the way to go about preventing this from happening.
Fantastic experience: Nav is an amazing instructor, his driving techniques are excellent. I passed my exam in first attempt yesterday. He is very punctual and efficient instructor. He accommodated my practice lessons to match my work schedule that has helped me a lot. Definitely recommend him.
Fantastic experience: At age 50 some people think no need to learn drive. But I want to meet the goal. I cached it. Because of you are amazing instructor how well you explain everything. I feel very happy achieving this milestone. You make students being successful and happy. There is no other instructor who does it better.
Fantastic experience: First of all I want to say thanks to you Nav for your help to pass my husband’s test in first attempt.We tried to call many instructors for lessons,because my husband’s test was in 3 weeks time so everybody said no we can’t give lessons, at least book lessons one month advance but then we found his number online and he agreed to give lessons .with his good teaching skills my husband pass in first attempt.Thanks once again.Navar
Negative experience: one star is also I'm giving because there's no option less than one star. I would say it was worse then a star. The instructor was so so rude to me when we met, and after that, he asked for money straight away. Because he was a little late, I asked, is this counted from the time, and the second question, because he was going to a second place for training? I asked, is this all the lost time counted?? It's a normal question he could have answered nicely, but he got me out of the car in a bad way. No professionalism, the worst person I've ever met.
Fantastic experience: I called Nav because of the great reviews he has and I am really glad I did. I passed my driving test yesterday, first attempt with only three minors and all thanks to Nav's wonderful driving lessons. He is very patient and understanding, a great instructor and a great person. He was also very punctual to all our lessons, and he explained my mistakes in a calm manner and how to improve my driving. I can't recommend Nav highly enough. Thank you Nav for all your support!
Thank you Ana you are a great student too
Fantastic experience: First of all I would like to say thank you to Navam, for guides me and teach me how to drive in a proper way on the road. I strongly recommend Navam to teach driving if any one want to pass in first time. He is the person who can teach you all the techniques. I pass my exam without any problems.
Fantastic experience: Have just passed the test in my first attempt with Mr Navar. He is a brilliant driving instructor, very patient and relaxed. I was really nervous initially and very bad at coordinating, he helped me a lot with his slow and steady teaching skills to easily understand, lessons felt comfortable and I was able to progress at my own pace, that saved me a huge part of struggling time. He really went above and beyond to help me calm and be confident for the test. Best thing in him he is Punctual. His instructions are very clear and explained all the rules that gave me confidence to drive safely. I would definitely recommend. Thank you Mr Navar.
Fantastic experience: Great instructor. I just passed my test today with Mr Navar. Very helpful and works on minor details as well.
Fantastic experience: I pass from first attempt...Great instructor...Great and patient men...Great carracter...thank you...five star
Fantastic experience: Nav is a amazing instructor, very straight forward and timing bound personality. He provides a very transparent feedback which really helps us to improve and understand our mistake. The techniques he suggested for all the maneuver was very easy to understand and follow. Would strongly recommend Mr. Nav for anyone who is really keen in passing the test in first attempt. Thanks NAV for all your support and bearing with me cheers
Fantastic experience: today i have passed my driving test at first attempt Because Navar is excellent teacher must recommend anyone who is looking for good instructor Navar is the BEST 1
Fantastic experience: Nav is very professional and flexible with the timings and honest with the feedback. His tips and tricks helps to improve a lot especially about roundabouts. Mock tests were very effective. I strongly recommend him.
Fantastic experience: Navar is really the best coach you should expect. I was told that I would never pass the driving test in the UK by another coach before Navar. Because I was used to the driving rules in China and not familiar with the UK driving habits and conditions. And then my friend Grace recommended Navar to me. He is really a great coach who explains everything and every procedures very clearly to you. All you need to do is to remember and follow his standards. He only arranges you the lessons that you need and would encourage and help you get a test as long as he thinks you are ready. So you should never worry about he charges you for too many meaningless lessons(which was the experience I had with another coach). I am a very casual person so I didn't expect I can improve my driving skills so quickly and get passed so fast. At beginning, althrough I had some lessons with another coach, I still feel very unclear with the things I need to be cautious about during the test and also the paticular maneuvers that will be tested. But after only about the 8 lessons with Navar, I feel I was very clear with what will happen in the test and also every details. In addition, Navar is really a kind, humorous and patient man, you will have a very pleasant learning experience with him, and also a lot interesting talks about the international situation and history
Negative experience: He has more experience, no patience at all,he is very rude, when a mistakes happen he starts screaming and swearing, which makes you fell stress and forget everything, I don’t want to say if he is too old to be an instructor but for new learners I will never ever recommend him.
Negative experience: This one star is also I'm giving because there's no option less than one star. I would say it was worse then a star. The instructor was so so rude to me when we met, and after that, he asked for money straight away. I said I pay you by card but he said no so again I went to my house and bring money and then he said “you are not at any parlour to cut your hair, give me money”. No professionalism, the worst person I've ever met.
Fantastic experience: I am super happy with the driving lessons, I thought I would never be able to pass a driving exam on the first attempt and it just happened yesterday. Nav is a great instructor, his tips and methods are infallible. He explains everything in such a good way so it’s easy to remember. Very patient and understanding. It was such a lovely experience and even though it was stressful for me it paid off - I have a driving license. Thanks to Nav who went with me hundred times through two mini roundabouts and still was patient and smiling. Teaching a blond one how to drive is a hard work ;) and he done it with success. He is not only a good instructor but also a very nice person. Highly recommend to anyone.
Negative experience: Not a good experience with him, he was rude and I had to stop after one class,
Negative experience: One of the worst experiences, he’s very rude, just because i swapped one class, shouted at me and left me on the road all alone and also took the money. I will never recommend anyone to take his class. Please first check properly with others before taking the driving lessons with anyone
Fantastic experience: Navar is the best instructor, he doesn’t cut corners and enables every student to become the best possible driver to the best of his ability
Fantastic experience: Passed my driving test in 1st attempt. Nav is professional instructor and helped me with all required guidance. The Mock tests with Nav certainly helped me to boost up my confidence. I would highly recommend Nav as good driving instructor. Thank you Nav!
Fantastic experience: I passed my test with only 2 minors in first attempt. You can never go wrong with Nav. He is a very patient instructor and will go an extra mile to ensure you do it right. His techniques are brilliant, simple and very accurate. He will make you familiarise with all possible test routes and manoeuvres which helps build confident and made me comfortable during the test. Mock lessons provided great insights and helped me fix the silly errors. I would definitely recommend him to anyone looking for a great instructor to pass the test in 1 attempt. Thanks Navr :)
Fantastic experience: Nav was the perfect driving instructor. I previously failed two tests with another instructor and Soon realised that Nav’s knowledge and attitude were essential in helping me to pass my practical. His ability and patience are extremely good.
Fantastic experience: Nav is an excellent instructor whether you are starting from scratch or wants to improve your driving skills. Nav explains everything in detail and always ensure that you have understand appropriately. He provides feedback in detail in every lesson what you have did better and things to improve and especially on next session/class he makes sure that you got it right which you made a mistake last time. Nav's clear instructons and intense training helped me to pass the driving test and developed me as a confident independent driver without fear or hesitation. A huge thanks to Nav and I would highly recommend to anyone who would like to pass at first time and become a good driver.
Fantastic experience: Nav is an excellent mentor and fantastic instructor. Because of Nav's excellent training and coaching, I passed my driving test in one sitting.Taking driving lessons from Nav was the best decision I've made regarding 'learning to drive, and getting pass'.

Fantastic experience: Nav is the most passionate driving instructor I have ever seen, he loves to teach in a supportive manner and professional. He never sits silent during the lesson, always try to guide us by explaining what is happening on the road, hinting to watch the sign boards. He used to encourage and motivate when I was nervous. Finally I passed my test in 2nd attempt. Big thanks to him. I would highly recommend him for any learner.
Fantastic experience: I'm a better driver today because of you. You're attention to details and your coaching is what I needed to be a better driver not just passing a test. I'll recommend you anyday. Much appreciated.
