Just so I’m clear on things… the problem is that your professor posted an assignment, you didn’t do it (or didn’t see it), and your gpa dropped from 4.0 to 3.7, and this is a problem because you’re applying to a scholarship and a 4.0 would be better. Right?
If other people didn’t see the assignment either, talk with them to the professor and try to see if you can make up the assignment. I think that would be your best bet.
