I'm taking PDD in 2 weeks and as I'm going through practice quizzes/exams, I'm getting overwhelmed by the number of formulas there are. Brightwood especially has a lot of formulas that I haven't quite gotten the hang of yet.

I'm just wondering if knowing/memorizing all of these formulas is necessary? I've been trying to understand the relationship between different elements of the formulas, so I can answer certain questions, but I just don't want to be caught off guard with trying to solve for specific values.

Any input is appreciated!

Thanks!
