I got GC OC and QR covered for now and here is what I did:
GC/OC: watched CHAD's videos, printed his outlines and took really good notes, and did all his quizzes, then I wrote down on flashcards all the things that I need to memorize (strong acids, strong bases, some naming, random laws especially for gases), pretty much everything I need to memorize, then I went over them twice and did destroyer. I didn't time myself, but wrote down all the things that I didn't get right, and the major concepts that I didn't fully understand yet.. all the things I got wrong and needed memorization, I wrote down on flashcards and added them to the packet, all the concepts: I just looked them up online! now I kinda understand all the concepts and have all the things that need memorization on flashcards! I am gonna start practice tests this Friday and will go over all the concepts I didn't get after each test, in the meantime I will be going over my flashcards!
QR: I watched CHAD's videos, printed the outlines, took detailed notes and did the quizzes, made flashcards then went over the first 10 tests of Math Destroyer, I made more flashcards and discovered that my only weakness is probability (I hate it!), then I went over DAT destroyer for QR and got 35+/40 rights on every 40 questions.. so now I am gonna try to understand probability really well and go over flashcards before the practice tests!
I hope this helps! good luck!
