I’m rooting for you, kid. Seems to me there’s three options:
Option 1 - Stay at your current, end the year strong in 10th, have an awesome 11th and first semester 12th and crush it in your sports. Get in touch with coaches as soon as possible and do the camps etc., to gauge your real recruiting prospects.
Option 2 - Transfer and reclass at another HADES, possibly get A’s and B’s (mostly B’s, but in tough courses for a soph) your second 10th grade, have an awesome 11th and first semester 12th grade, have even more rigorous coursework (more later on that) and have an additional year of crushing your sports.
Option 3 - PG at another HADES (which I can’t say I’ve seen that much), have all the benefits of Option 1 with a full 12th grade of grades and sports (including insight into the recruiting opportunities), and an additional semester of grades to potentially help shore up GPA and additional rigor.
On rigor; again, I’m thinking you’re too wound up on the math bit. It sounds like your rigor is more than demonstrated in your other non-math courses for a tenth-grader, unless I’m reading this wrong. It’s funny to me how some kids equate rigor with whether they take Linear before they graduate (including my kid who was embarrassed that she took the Math 101 equivalent at her school that is comparable to yours yet will be taking an AP Music Theory course her freshman year). Rigor is holistic. Don’t get wound around the axle on math.
This is one of those “family discussion” responses that is sometimes unsatisfying, but at the end of the day…
Good luck.
