I met ravi with no knowledge of driving besides a very bad driving session with a different instructor and a semi-lesson with a friend. I had no confidence and would constantly place my foot above the break pedal even if the road was clear. Ravi helped me overcome my initial fear of driving and helped me gain the confidence and road smarts to pass my test first time (which he did promise me even before we started).
I highly recommend ravi because he was funny,encouraging and patient with me and helped overcome my faults and improve them in only 26 hours of my intensive course.
Only thing to worry about is the occasional dad joke he says the day before your test (:D ) Overall: if you have ravi you will have a excellent chance to pass! Just bring a willingness to listen and learn from constructive critisam and a winning mentality.
