How would you recommened the AOPS introduction to algebra book on a scale of 10?
I’ve been thinking of buying one for myself, is it worth it? I have a bit of algebra background since im still currently in highschool, but haven’t really gone in depth in said subject.

Please try the official diagnostic tests for intro to algebra A here at: data.artofproblemsolving.com/course-docs/diagnostics/algebra-a-posttest.pdf and then intro to algebra B here at: data.artofproblemsolving.com/course-docs/diagnostics/algebra-b-posttest.pdf If you can solve nearly all of the problems there with little difficulty, then you could probably move on to the next level.
