EbbinghausAfter ClassBeat the Curve

Forgetting curve would start here if we could remember everything after a lecture

Forgetting curve would actually start here as we typically remember only

about 75% at the end of a lecture – so we have less to remember

However, you have the potential to forget less PLUS remember more if you review immediately after class

So Review 10 min - After class (or in evening) by completing, organizing & comprehending (rewriting, typing) notes (e.g. Cornell right column)24 hr – Next day, before Ebbinghaus kicks in, reread notes, condense to main ideas & create questions (e.g. Cornell left column) 1 week - Before class the following week or earlier, review and self-test your recall (e.g. Cornell, cover right column & self-test from left)Therefore, when you prepare to study for your midterms and finals, you have already reviewed the material a minimum of 3 times
