If it is anything like accg105, we had a practice set but it was Ants Pants, which I think is similar to safari, the questions they asked on my finals on the practice set did not involve you knowing the resulting values of the BS and all that. But you had to know who the buyers, sellers were, what kind of things the company sold, and like general stuff like that.
They never asked us to fill in blanks on the BS, so you weren't really needed to memorise any values, just pretty much the functions of the company
