When to Memorize Formulas? Schweser Notes

So I realize it’s probably a little late for this, but when do you guys think is the best time to start reviewing the formula sheets with the Schweser Notes? So far, I’ve been reading all the chapters and answering the questions without any attempt to memorize the formulas. I’ve been averaging 65%-70% on most of the question sets, but I’d expect that number to get higher once I remember more than half the formulas. Should I just save the memorizing formulas part until the last 2 weeks and cram?

I probably should have thought about this before I read 4 out of 5 of the Schweser books. I took off from school this semester to study, so I have plenty of time to cram. I’ve put in about 190 hours thus far, but still feel there is so much I need to know.
