@Lego100 it is doubtful that you will get a 36 and therefore, due to your school’s misguided policy, that you will be valedictorian.
I would not stress over rigor, grades, or scores since they only are used to meet benchmarks at top schools. It seems you are going to cause suffering for yourself for no good reason in terms of outcome.
What do you do outside of the classroom, as an extracurricular in or out of school? I think that is a more important question.
Remember that admission is not hierarchical in the sense that an SAT score of 1580 has a better chance than a 1520. Etc. Instead top schools are assembling a class and want an interesting mix. There are a lot of applicants with great scores, grades and rigors who do not get in and those who do probably satisfy other factors that add to that mix (or are athletes, legacies).
Enjoy your last year of high school!
