Good example in my math and physics classes I found it really helpful to understand the general concepts, then instead of memorizing formulas could actually derive them from other known (perhaps easier-to-remember) facts.

Geometry is good for training in this way—and often very helpful for physics proofs too!

Too bad this method is penalized most on tests (timed) where memorization is favored. But deriving results reinforce knowledge, understanding and patterns best in my opinion.
