So this year I have gotten a B (85.4) in AP Calculus q1, and a B- (82.3) in q2. I haven’t had my midterm yet, but I expect to get a B as well. Overall, my school reports final grades, not semester grades. I was wondering if my mid-year report will separate my grades (B q1, B- q2, B midterm) or combine them into one cumulative grade (B). There’s a chance that this differs by school, but I haven’t found information online to let me know. Thank you 
Your midyear report will likely show the grades you got in Quarter 1 and Quarter 2, assuming your midterm is factored into your Quarter 2 grade.
