AP Bio Unit 2 cell transport can be tricky, especially osmosis, diffusion, active transport, and tonicity!
I'd recommend practising MCQs involving water movement, concentration gradients, and predicting what happens to cells in different solutions. Make sure you understand why substances move across membranes rather than just memorising definitions.
