- I took biology and had her teach me in both grade 11 and 12. Biology is a very heavy memorization course but if you study every night (not rigorously, just look over your notes / read them over twice) then by the time it's test day, you can recite the note like the back of your hand (repetition repetition repetition!!!!! ) - Watch Crash Course Biology on YouTube because it helps visualize the stuff you learn about (be careful it has a little more info than we need though) and the host is entertaining to watch - Make sure to understand how things work together (like how the entire photosynthesis process works together) and not just blindly memorize because the big questions on tests require thinking and applying that knowledge to other situations and you need to understand the what and the why!
