You're hardly a committed, studious person, are you?
Unless you knuckle down and actually learn how to drive properly with plenty of hands on as well as theoretical experience with the understanding that goes with it, you're just setting yourself up for another fail. £62 down the drain.
Anyway, to answer your question, RED driving school will probably agree to take you for a test after hardly any lessons; they bring any old ****e along for test. If you want to pass the test, then you really need a good instructor and a lot of lessons in a short-ish time.
