Formulas are not enough on their own
A cheat sheet is a reminder, not an explanation. Use it while you practise so that looking a formula up becomes recalling it, then try a problem set without the sheet to see what has stuck.
For the reasoning behind each formula, worked examples and common mistakes, read the matching study guide, then test yourself with practice problems.
