question for ppl who took chem 30

what was the cutoff for an A in the class? like what was the number grade for an A- vs an A? is it safe to assume that a 93 is an A? for reference our class average for the last two exams has been a 68%…

hope someone can give me an answer if they remember from when they took it. don’t want any snarky replies tho pls 🕺🕺🕺🕺
