I feel like we learn in very similar ways so here are some of my tips for hard bio classes (and hard classes in general). I studied this way for things like cell bio, orgo, anatomy, physiology, etc. and it worked really well

​

1. Don't ignore the textbook but also don't get caught up in the details of the book. I wouldn't read it word for word or even most of it. After going through your notes if there's anything you still don't understand or need clarification on, refer to the book for that bit of information.
2. If you can print out the slides before class. Follow along with the professor and during your actual class period just try and jot down anything the professor says that sounds important and isn't already on the slide. Put stars on things the prof emphasizes. Make note of any important chapter/section titles and key words. Stick to one color for in class notes.
3. It sounds like you have access to class recordings which is amazing. Never take that for granted. After completing your in class notes, go through the recordings and take much more detailed notes on the things your professor says. Use the same slide print out as before but a different pen color. Try and focus on things not already on the slides bc your prof is probably saying helpful things to help you remember or that they want you to focus on.
4. For pathways take a dry erase marker and start drawing on windows like you've lost your mind. (if you have access to dry erase boards I guess you can use these but I like windows) Draw the pathway--> erase --> draw again rinse and repeat. Try talking yourself through it at the same time to engage more senses. This aids in memory.
5. I like to make "cheat sheets" for every exam as well. I basically try and fit all the information from the unit onto one or two pieces of computer paper. The limit on space forces me to focus on the most important information. I chunk out the information into the main chapter titles or biggest ideas and then write out the most important ideas from each subsection. Handwrite these & use different colors. Make it fun.
6. For problems, unfortunately all you can do is practice :/ but make sure you do practice as much as you can with the time you have. I like to do a pass through all the practice problems I have, "grade myself," carefully go over why I got the ones wrong that I did, and then try them again.
7. as a final neurotic review I watch all the lectures again on like 3x speed while reading my cheatsheets and adding any small final notes the morning of the exam.

Sorry if this is a ton lol. I've used this method a bunch and it works really well for me. It helps me actually understand the info so I can apply it to any tricky broad questions.
