As you are working through the review, keep a sheet to write down formulas, constants, ideas & processes that you tend to forget or confuse, THEN make out your notecard from that sheet. Don't overfill the notecard. It is there as a reminder and security blanket. It doesn't help you if you can't find anything on it.
