Hardest unit in AP Bio?

To my fellow AP Bio students, in your experience, which unit in AP Bio do you find the most difficult? I'd like to brace myself for what's to come and allocate more study time to challenging units.

Hey there! In my experience, the most difficult unit in AP Bio for many students is Cellular Energetics (Unit 3). Cellular respiration in particular involves many complex processes, such as glycolysis, the citric acid cycle, and the electron transport chain—and the unit requires understanding how these processes are interconnected.

It can be overwhelming at first, but breaking it down into smaller sections and using resources like review videos or practice questions can really help with understanding. That being said, every student is different, so you might find other units challenging as well. It's great that you're planning ahead, and I recommend keeping an open mind and continuously assessing your understanding throughout the course. Best of luck!
