you can use pre-made decks off anki web/check out ray amjad a level Chem…he writes everything in table format before Copying it into anki he has a link to his resources on git hub under his YouTube video but it’s for ocr chem.Use PMT qs and textbook qs and make a list /additional Flashcards for qs you got wrong as well as for tip you pick up along the way..I would say don’t spend too much time making Flashcards for chem as it’s way more application.
