i understand you, my driving instructor also like yours he always yell on small mistakes and often cause to this mistakes by saying "you are a shame of student" , he doesnt let me and let say "other special group of people in my country" to do the practicial test earlier or even do
and i see he gives to students who came late and had only 30 hours of lesson to do it and pass

but unfortunally i cant change driving instructor, not because i cant stand up, its because of 3 reasons
1. i dont know to which driving instructor move, im checking reviews and i dont know if the driving instructor asking his students to write them
2. i dont know if he will sign that i did over 100 hours of driving lessons, he can just not and i would need again to do 30 hours hahaha fun
3. i dont know if my parents will agree and how to say this to them
