I agree that studying the formulas is important (and is useful in FAR and AUD too), as they are most likely to show up here. Becker tends to be a bit too difficult with questions by giving you 50 different sets of facts, and then wants to know if you can calculate... days sales outstanding. I found the exam to be a bit more precise, you just had to know how to move around the numbers.
But be careful, logic doesn't always help. Switch a numerator and denominator, and that's choice A and B... forget to include something (or something else maybe added or used, or may have/should not have been calculated) is C and D, with the same A/B switcheroo. So if you really have no clue with what goes where, you may not be able to "eliminate" answers, and ALL may be right. (I generally tried to solve for other possibilities with my equations, and found in some instances, I can come up with A, B, C, and D... But not in all instances, so I knew my answer was good then!)
IT was also very heavily tested, as it was indicated.
Economics wasn't nearly bad at all, so if you understand the jist of things, you should be fine.
REG - 97
BEC - 82
FAR - 86
AUD - 96 ... DONE!
