SDN Members don't see this ad. (About Ads) I keep finding myself forgetting things I have spent many times memorizing over and over since at least college. Like say the intricacies of G-proteins, or even the amino acids. People say repetition helps with longterm memory, but it doesn't seem to help me. Each time I memorize, I feel like this time I've finally stored it for good, but it's never to be. In the end I still forget my damn amino acids after six months of disuse (like for Arg, Lys, Met). Some things just don't retain in my long term memory even though I've tried to memorize it at least half a dozen times (writing it down, using flashcards, testing myself). Am I alone in this or is this pretty common? I do tests just fine, my short term memory is excellent. But I'm so tired of wasting time refreshing my memory on things I have no excuse for forgetting anymore. It's embarrassing too. Ugh. What to do?
