Although I didn’t take it, there’s an organic chemistry class at my school that has lecture from 1:30-2:45 and lab from 3:00-5:00 every Monday and Wednesday. I have a physics class that meets for three hours twice a week this semester.
I think those are the longest classes I’ve seen at my school.
Are you sure those numbers are accurate? That seems very excessive. Is this a regular thing, or has it only happened once or twice?
edit - The greatest number of papers I’ve had to write for a single class is five, in English Composition I.
