A "-1" in a lab column indicates that this lab (that you did
not do) was your dropped lab. If you don't have a -1 in a
column, you did all the labs and your lowest lab grade is
automatically dropped. (Same with HW/Quiz.)
Please recall the final grade deductions (see syllabus) for low scores on homework/quizzes.
You can view your exam in my office through the first month
of next semester, but I will not return the exams.
