they can be a but hit and miss really. I had had about 20-30 lessons over the years as i kept running out of money so when i had saved up a few years later i paid a whack of money out and did an intensive course. I did 4 hours a day for 5 days and then they want to put you in for your test. My instructor was an old man who was rubbish and shouted at me a lot. I felt totally under-confident and not ready to sit a test. They told me that if i failed the test i would end up forking out a further �90 in total to re-sit, as i'd have to pay for hire of the car etc... so i decided to have some more lessons.......but this never happened as i had no money left!! 5 years later i learned over 3 months with a reccommended instuctor (by a friend) and passed 2nd time! (He was really good with me) It depends on the instructor and how confident you are. My boyfriend had also had lessons in the past and did an intensive course that his work paid for and he passed 2nd time. (he is a really confident person when it comes to things like that tho, hes one of those who thinks he can do it even when he cant!) I would go for gradual learning as it doesnt have to take forever and its practice getting used to everything thats the key to passing......if you do it intensively you often dont feel youve had enough experience behind the wheel.
