Forget memorization. It won’t help you now. The only things you should be memorizing are common names for benzenes with substituents, and ochem 1/gen chem stuff. Do not try to memorize the reagents back and forth.
Classify reagents by what they do! Are they ortho directors? Will this turn an aldehyde into a carboxylic acid? Does this perform addition to the most or least substituted carbon? Classify them HOWEVER makes the most sense to you, and look for patterns. If you can’t find any among some, find a new classification they fit in.
Track reactions. Understand every part of the reaction. Don’t make a single change in a molecule without knowing why it happens. This is a huge reason I use whiteboards – I can mark these things in different colors over and over and over.
Practice problems. Do everything your Organic chemistry tutor gives you. Have an MCAT prep book? Do all the ones in there. Look them up online.
