This is a live math test, like the others that I have submitted. The professor will upload the questions, and I will screenshot them and submit them here. Please answer back with 2 at a time. The test is Wednesday, June 9, 2021. Starts at 10:20AM Eastern Standard Time and ends at 11:00AM Eastern Standard Time. Worth 50 points again. Probably the 11-13 questions again.
