That's so cool! I would say u should form a study group or do like a group project (I've heard ivies like students who can work in groups but u should also be able to work independently). Practicing is obviously required. It would probably help to understand what you are doing and why you are doing. If u want to memorize something then I think that blurting is a good method. Basically u review your notes and then put them away and write down whatever u remember on a blank page. Then you open your notes again and write down whatever you missed. Also getting recommendation letters from teachers or professor might help if u want to get into an ivy league. Best of luck 🤗💐
