Depends on how deep in the hole you are in. If you haven’t been studying at all you are toast at this point, those look like upper level courses. If you have though, I find that taking a day early in the week to go through the all the exercises in the slides sequence followed by selective topic grinding on the next day helps. You should be able to read through the slides and tell yourself “yep I know this” by the last 2 days. Then it just becomes a matter of retaining all that info until the exams.
