Hi guys,
A bit of a fundamental question really - sorry

With regards to revising what works best for you folks? There are probably some folks here who can read something once and it stays imprinted in the mind. Unfortunately my brain is not wired that way.
What Im asking is, when you're studying through for example - Mike Meyers All In One Fourth Edition, are you making your own notes along the way before the end of chapter test(s)?
Any hints and tips would be really helpful
