I am taking driving too, very demoralised too! From starting, it's a very bumpy road! To be frank, I reallly regretted taking private as choosing the right instructor is really very important, my 1st instructor was very "dilly-dally" and bo chup!
By the time, I took my 1st test, it's almost 10months! and I only learnt vertical parking 3 days before my test, as a result I got a instant failure in my vertical parking for taking over 3mins to adjust my parking (parked too near the curb).
My 2nd instructor was great but I changed the driving centre hence need to learn the route from scratch and what he taught was totally different from no. 1 and it's very hard to adjust my bad driving habits.
