Madgav,
Keep working on those crosswind landings, as you really will need them when you qualify (otherwise you'll never get to fly).
What type(s) are you training on?
What exams have you done? Obviously you've done Air Law...Human Performance and Limitations is easy, I had a little ground school for Navigation and Radio Telephony...I just used the confuser for Meteorology and Flight Planning. The one I found hard was Air Tech/General (whatever it was called)...but clicked in the end and the PPL Confuser helped.
Like I said, don't let work get in the way...whenever you go up to your club and get weathered off, get some ground school instead and do some revision and get another exam.
