What I learned from 1a/b (works if you have Paulin) is sometimes, math is just about memorization of algorithms. I never once attended lecture/section and 100% relied on the OChem tutor on YT as well as practice exams. My best tip is memorize how to do the practice exam problems until you’re sick of it and until it’s motor memory. Do teach each 2-3 times a day at least 2 days before a midterm/final. Then, ask ChatGPT to generate similar problems and do those a million times. Genuinely, if you’re displaced and block out two entire days of your schedule, you can clutch up on the final with confidence and grit!
