When I built my 486DX2 in 92, with huge help, my guru said to get 5x7 spiral-bound recipe card set to act as notes that he'd mention, as we go. It worked great!
I had the reference, and writing things down, acted like the only cheat sheet I ever made. Completed, I didn't need it. Writing it down after mentally condensing it forged the memory. Never repeated that, sadly, as it created my best grade ever.
New blood sees things with an unjaundiced eye. Making your own note-set, helps. It's a lil laborious, but almost a one-off.
