My story is funnier, at first I got a Chinese instructor which was kind and experienced and pointed me the right way then he passed away before I finished my practical lessons and the school changed a Malay instructor for me, which was also kind and good, more lenient than the Chinese one but at that point of time I already picked up all the skills I need anyway.

Again, you either live with your current instructor or request for a change. If you are really making mistakes though try to ask your friends/parents to guide you at home, sharpen up your driving skills so the instructor got nothing to nitpick on
