Hi guys! Theres been quite the debate in the comments on what grade Sierra and Sam are in, I just wanted clarify that they both are seniors in highschool. The grade you do each level of math in depends on what school you go, but Trig it is typically for sophomores who are 14-15 years old. I chose a lower level of math to show that Sierra was really behind in school and needed to take steps backwards in order to graduate. I’m sorry for any confusion and I hope this helps! Thanks for reading!
