Neither of mine are great math students. S19 was on a fairly accelerated tract in middle school, but moves and curriculum change (thank you Common Core eye roll ) he ended up re-taking Alg 1 as a frosh and Geometry as a soph in HS. His ACT math splits were never spectacular, but he got into a really great school. Just focus on what he’s best at, and maybe get a little bit of help where needed (sounds like you already are). I wouldn’t push for a tract he may not be ready for.
