reef points - what to memorize?

Hello! Just finished up my week at Summer Seminar, I love it ten times more than I did before (and that is saying something)!

As per the recommendation of an acquaintance, I picked up a copy of reef points. Since it reads like a textbook, and doesn't clearly define what needs to be memorized verbatim, I was wondering if anyone on here could help give me an outline to help prep for plebe summer.

Thank you!
