> I need to keep on relearning basic concepts I should have at the top of my head. Who says you should? As an engineer you are a problem solver and not a hard drive to store every step of an algorithm. You seem to know what pieces fit together but struggle with the details, but that's fine. It's not a negative thing, you are just a bit hard on yourself. If you don't use a concept regularly, you are naturally bound to forget it.
