Hi Mistrol
Just to help you clear the air a little, I paid around that price as well. Which is:
1) $32 for peak hours (1-hr lessons)
2) $52 for Circuit + normal lesson (30 min circuit, 30 min normal lesson)
3) $266 for test date (Rental of car, warm up etc)
In total, I did 11 practical lessons incl 3 circuit training. Spent a total of $600. Passed on first attempt.
I've read in other threads that some students had to go through many rounds of practical lessons (e.g. 30-70 lessons) which to me, is really quite a lot, but that also depends on your driving skills. I'm quite sure the instructor would know you best and advice you approximately how many lessons you require, what are your weak points etc.
Do let me know what other info you require.
Good luck!
