Here's what I've come to realize about all of these formulas, and it comes from having taken the test once and having done a lot of EOC's:

Unless you're a financial genius and you know how to derive all of these formulas from their base concepts, don't bother. These formulas are given separately because they are all tested separately via the format of each question.

From the OP, you'll be given a question that has the components necessary to answer via formula #1. Sometimes, the question given will have the components necessary to answer using formula #2. It's just that simple.

Like I said - if you have a *very* good understanding of the material, you can work around just a few formulas and come up with the right answer to the problem set. However, given the time constraints, you're basically being asked to recall a specific formula/concept and apply it as directed.
