I’m a bog supporter of flashcards for equations and simple but harder-to-remember facts. For equations, I always have the name on one side and the equation itself on the other. Then I try to reproduce the equation blind.
Dropping out the cards you know well as you go saves ploughing through well-known territory, but consider chucking them back in and starting again at some point with the complete deck, or you might forget them after all!
