June 28: Midterm Grades -- Due to the chaos caused by relatives moving in with me this weekend, I haven't had as much time to grade exams as I'd hoped, and won't finish grading the exams by Monday. However, I will return any tests I have graded at that time, and the others as I finish them (hopefully, no later than Wednesday).

June 26: The first Midterm was tonight -- If you missed it, you can still pass the class if you do well on the remaining exams, since the first exam is only 20% of your grade (and as discussed in the Syllabus, if you have time, you can take an extra Final on July 24, to replace a missing or poor exam). However, if you did miss the first midterm, you absolutely have to take the second midterm, or you will be dropped as of the date of that exam (July 10).
