Ok so i just got through with M 427K with Lock, which was a ridiculously hard class compared to the other diff eq classes my friends are in. He does not post our grades online, curves the final grades at the end of the year, and doesn’t tell us what the class averages were for each test, only gives us rough estimates of what the curves will be for each test. Long story short, my calculations put me on the boarder line of pass/fail and i didn’t do great on the final. I know the material, and have looked at what is required for phy 315 and can do the math for it. My question is, if I study a good bit over the summer and basically learn the class, can i get the professor for 315 (Fitzpatrick Fall 2015) to give me a waiver or something allowing me to take the class in the event that i don’t get credit for M 427K. I plan on retaking the class next semester if I fail, but i don’t want to be behind a semester because of a few points.
