One of things I took out of Accounting this year, was practice. In many ways Accounting, is like Maths, you just do the exercises - and the more you do, the more likely you'll get better. If anything, just have notes on the theory for each chapter - have a separate exercise book for theory notes.
Generally, there is more prac than theory on the Unit 3 & 4 exams (~60% prac, ~30% theory), though this can change each year. Theory is main area which separates the A's from the A+'s (hence, my score). The practical side of things - most students will pick up, it's the theory that gets students. Theory may only be worth 30 or so marks out of 90 on the exam, but it's very important.
Good luck Accounting students of 2011! I'm hoping and expecting you guys to better my score of 37 - all of you should at least get above 40 for Accounting with the resources here. If you are in need any assistance, ask myself or ask Sammy (sam.utute) who got 47, _avO who also got 37 or davyp3 who got 40 (and is also willing to tutor in Accounting) - those guys are willing to help out, as am I.
