When's your b-day, at the beginning or end of July? I know some people who managed to pass within 6-8 weeks of starting lessons, I think it really depends on how many lessons you have a week. If you can afford it, which is a problem as they are pretty expensive, if you can have say, 6-8 hours a week of lessons, and manage to get some private practice in as well, I should think 2 months would be long enough to get to test standard. All depends on how fast you personally pick it up. Good luck!
