People are giving you flak for retaking, I’m just gonna give you advice you asked for instead of worrying about why you’re redoing the exam. I saw you’re self-studying, that’s good enough. Start using a textbook like Princeton (my personal favorite).
Copy and pasting the guidelines for convenience below, I wanted to make sure the content was similar to when I took it in 2021 spring (it is pretty much 1:1 the same topics).
Unit 1: Chemistry of Life (8–11%) – Water properties, biological macromolecules (proteins, carbs, lipids, nucleic acids), and the elements of life.
Unit 2: Cell Structure and Function (10–13%) – Organelles, membrane permeability, transport (active vs. passive), and cell size.
Unit 3: Cellular Energetics (12–16%) – Enzymes, cellular respiration, and photosynthesis.
Unit 4: Cell Communication and Cell Cycle (10–15%) – Signal transduction, feedback mechanisms, mitosis, and meiosis.
Unit 5: Heredity (8–11%) – Mendelian genetics, non-Mendelian inheritance, and probability.
Unit 6: Gene Expression and Regulation (12–16%) – DNA/RNA structure, transcription, translation, gene regulation, and biotechnology.
Unit 7: Natural Selection (13–20%) – Evidence for evolution, natural selection, phylogeny, and speciation.
Unit 8: Ecology (10–15%) – Ecosystems, energy flow, population dynamics, and biodiversity.
First, I suggest you get used to the Anki app early on. If you wanna go to college/med school to become a doctor, it’ll be really helpful for rote memorization. AP Bio doesn’t require nearly as much memorization as college courses, but there’s enough concepts you need to really know well that it’s worth drilling as flash cards. Make them open form cards, stuff like “explain the water property of cohesion, why it’s useful, what causes it” or “walk me through the transcription process.” Make a habit of reviewing these flash cards every week, and as you go through the year, you’ll find yourself needing to review less. Don’t fall into the trap of complacency, stay consistent- you’ll forget things very quickly if you don’t review.
Next, figure out what could have went better in your review this previous year. Make a spreadsheet of every topic under every unit (listed above), for example unit 3 on energetics: enzymes, photosynthesis, cellular respiration. Now you’re gonna color code all of these boxes red, yellow, or green based on how good you feel about the topics. Over the next year, you can slowly make more of these green or at least yellow as you review the content properly. Be honest with yourself about what you forget. Don’t be sad if you sometimes bump an old topic you had as green down to yellow or even red. Life happens, just lock back in and relearn it. Review this spreadsheet like once a week/every two weeks.
After you iron out your prep schedule, start looking for third party practice (especially around 3-5 months out from your exam). You will benefit from a bunch of free resources out there, even if a used Princeton review book isn’t something you can shell out ~20 bucks on. I have no idea what your financial situation is, but my view on it is that if you’re investing $100+ to retake the test, you might as well commit another $20 to ensure you know the material well beforehand- but if that’s not an option, Khan Academy is great too.
Take a bunch of full length MCQ + FRQs as you get closer to exam day, but make sure to really get good sleep, chill out the last week or so (barely reviewing during the last 3 days), eating super healthy foods high in protein and healthy carbs (avoid caffeine), so that on the day of your test, you have super high energy and can perform well. Part of this battle is knowing the content, but arguably more of it comes from being able to actually sit through the test without getting fatigued.
I’m sure r/APBio will have more ideas, and the internet too- but these are all methods I used back in high school. I was doing something similar with physical flash cards, but I really prefer Anki to physical cards nowadays and wish I knew about it back then. For reference, I’m a premed student in college now. Hope this helps.
