Fuckin Thursdays. I'm in a 160min lecture that started at 8:35, followed by a 160 min lecture, a 40 minnbreak, and then two back to back 70 min lectures. :(
I can barely do lectures longer than 50 min. 75 min is a major stretch.
Forget 160 min ones. Thankfully those are usually labs, which are better cause u walk around and stuff
