Yeah I know from my tutoring experience that first-year students need a lot of help reviewing the math material, or sometimes outright learning for the first time. It's a bit problem for anyone who crammed before the exam, and then didn't need to use the knowledge later on. I used to spend at least one or two sessions to review high school math before we can start on university-level topics like calculus and physics.

If anyone is interested in a condensed review of high school math, you can check out my "green book" which is just a few hundred pages, but has all the essentials of high school math, see https://noBSmath.com and the PDF preview here: https://minireference.com/static/excerpts/noBSmathphys_v5_pr...

Here is also a concept map that shows an overview of all the topics: https://minireference.com/static/conceptmaps/math_concepts.p...
