Yes - it was a question of getting my head in the books, going through the PPL Confuser numerous times (I believe there's something similar available now), and asking specific questions of my instructor if there was anything I didn't understand or needed explaining in greater detail. I also had the Oxford Aviation CDs to look at.
With steady, regular self-study, and asking questions pre- and post-flight, you'll probably find that you won't need dedicated ground school sessions. Alternatively, you could always tag a classroom session on to the end of (or before) a flying lesson.
Good luck with your training.
