Using spaced repetition systems to see through a piece of mathematics
Does anybody know a good math course covering all the high school and college subjects implemented in a collection of flash cards? I have no idea what do &quot;normal matrix&quot;, &quot;diagonalizable by&quot; and &quot;unitary matrix&quot; mean (of course I can look these particular up) mean so far but I feel like I would like to try learning up to this level (including what I&#x27;ve learnt in the college and completely forgotten right after the exams) this way.
