lol~ accg200 is reaaaally hard, but u jus have to study majorly for it; i redid all the tute q's and the homework q's and the textbook q's...also focus on the variances and...jus the areas they will tell u to focus on. also the calculations like..i cant remember..i did it last semester..u know the ones that take up a page? anyways and a bit of the theory but not too much.
i didnt do 201 but heard it is easy compared to 200.
