How to memorize the amino acids fast
Most students try to memorize all 20 at once and burn out. The trick is to group them by class first — nonpolar, polar, acidic, basic — then drill the one-letter codes separately, because those are nearly random and need pure repetition. This quiz is built around exactly that order. Run "Name → class" until it's automatic, then switch to "Name → 1-letter code."
