Where can I find math edu dataset?

I'm looking for data on students' math performance specifically data containing 1. how frequently specific concepts have appeared in exam questions over the past few decades (frequency of exam questions), and 2. how often students have gotten questions involving those concepts wrong (frequency of error). Preferably public data so that I can use it for my class project please. Thank you! submitted by /u/Whole-Yogurtcloset16 [link] [comments]
