Explaining Midyear Grades

Honestly, I really wasn’t that bothered by the B’s because I know that I tried my best. Things didn’t work out - oh well! But, then I talked to some people on Reddit and they essentially said that the senior year midyear report is probably the most important. I got a bit worried. I’m gonna refrain from explaining them, though. It is what it is, and my gpa is still 3.9+ and like a 4.8 W.
