I've taken quite a few physics classes over the years and I read about physics when I can. However, I always forget what I've learned. When someone talks about a concept, until I go review briefly what I learned, it's hard to remember things. How can I improve my ability to hold on to physics knowledge?

Every now and then, go back to the problems you solved in college and do them again. Redo them in new ways, if possible. If you've forgotten the formulas, take some time to refresh them in your memory. There is nothing wrong with forgetting stuff you've learned; it's normal.

Additionally, there are websites like Brilliant that package Physics problems into neat puzzles that entertain you while making you revise different concepts. The key to mastery is repetition.
