Advice will vary, but assuming you are using Coaching Actuaries, what worked for me was:
Going through the material, doing example problems.
Making a "handmade note packet" of formulas after going through the material.
I do this after for two reasons. One, some formulas become pointless to write down because you've used them so much. Two, the CA formula sheet misses some of the "intermediary formulas" I find helpful when solving problems.
Drill quizzes with formula packet. I'm not afraid to use it because it's better than being stuck and just looking at the answer.
I did this for both P and FM. Over time, I'd use the note packet less and less as I became more comfortable solving problems. It also still serves as a reference for memorizing closer to the test.
