Last semester, I did get all 90%+s, with my average across courses being 97.85%. This semester, I have 4 courses not yet guaranteed to be a 90%+ this semester, which are Business Technology, Intro Accounting, Intro Stats, and Calculus 3. I have found them all pretty easy, and I only need 70%-80%s on my finals to get 90%+, but I did get a 78% on my last Stats exam so it's not entirely safe.
I will resolve this market based on the letter grade I get on my official transcript (Needs to be A- or higher on all current semester courses). However, I track my grades meticulously, and if I think there is an error, I will try to clear it up before resolving this market, and will only resolve it once everything is 100% finalized.
I will not bet on this market.
