Hi there,
I'm currently an MS-I at COMP and we are in the middle of our second semester. The first semester, we would spend anywhere from 5-8 hours at school in class/lab.. probably averaging more about 6-7 hours. We have periods in our schedule where each week we would have an exam.
During the second semester, we don't have exams as frequently since we have started all our systems-based courses. I think we do spend quite a bit of time in the classroom.. probably 6-8 every day, but it seems like we will sometimes get a half-day on Fridays for what it's worth.
