Not directly CFA related, but an interesting piece on the BBC related to revision:
"Now if many of us were revising [...] we might study the list, test ourselves and then repeat this cycle, dropping items we got right. This makes studying (and testing) quicker and allows us to focus our effort on the things we haven't yet learnt. It’s a plan that seems to make perfect sense, but it’s a plan that is disastrous if we really want to learn properly."
