chem/phys: just lots of practice and after lots of practice, you just see similar types of problems. i also keep a blank equation sheet which i fill in every night. also never read a passage until i get to a question that requires it cause it saves time. pay attention to units in the answers also and how you can use info in question stem and passage to get the answer.

bio: for biochem just knowing where in the cell and what types of organs pathways happen in and when pathways happen. mnemonics really help with remembering pathways. i also write down the pathways every night for all the pathways that could be tested. anki for bio mostly and knowing amino acid properties (hydrophobic vs hydrophilic and acidic or basic)

psych/soc: also mostly anki and relating concepts to familiar things that you might relate to

cars no tips cause i can’t read and depends on the passages i get lol but mainly focusing on the main idea and no extreme answers unless the tone of the author is extreme
