Wowwwww, impressive! Breakdown please! 😀
PAT: DAT Bootcamp. All 10 practice tests, as well as generators almost every day.
QR: Chad's Videos, plus Math Destroyer has all the important formulas you should know. Practiced with DAT Destroyer, Math Destroyer, and Bootcamp QR tests, all of which were harder, but they get you into the right mindset.
RC: DAT Bootcamp. Most of the Bootcamp reading passages were harder than the actual reading.
BIO: Cliff's Notes, Feralis's notes, DAT Destroyer, and Bootcamp. Wide range of topics that could be asked, so it's best to cover everything. Some topics like Anatomy & Physiology is glossed over by Cliff's Notes, but between Destroyer and Feralis's notes and Bootcamp, you are good.
OC: Chad's Videos, DAT Destroyer. Chad does not go over everything you cover in a college class/lab (and he admits that), but he covers 90% of it and he does it well. For instance, Bootcamp had a list of lab tests for certain functional groups, but I believe Chad did not go over tests. The Destroyer has hundreds of questions and is
great practice and has very good explanations. The list of reactions is a good summary and is able to condense a year's worth of chemistry into a few pages.
GC: Same as above, but Chad covers probably all of what you could need to know for GC. Destroyer likewise has plenty of questions that both introduce new/underrepresented topics and also reinforce the really common questions that people sometimes underestimate in difficulty.
I studied all throughout this past break (approximately 4 weeks). Chad's Videos and Cliff's Notes in the morning, PAT generators/practice tests at night. Once I finished studying for a section (like OC or GC), I started using the Destroyer to see where I could improve. Marked every question I was not 100% sure of and redid them at a later time. Once I was fairly confident going through the Destroyer, I started taking Bootcamp tests, but I continued reviewing and doing Destroyer questions.
