USS · Revision
Twenty-two pages: seven quick references and fifteen topic pages. Every one of them folds down to its headings on a phone, so nothing is a blind scroll.
Ninety minutes tells you which topics are weak. Revising everything equally wastes most of the time.
The scorecard ranks them worst first. Start at the top of that list and open the page for it.
Ten questions with the explanations read is worth more than reading the page a second time.
