Last Thursday I took my first midterm exam in, oh about 15 years or so, in my Biomaterials class.
I think one of the hardest things so far about taking classes again is that I have to actually learn and remember the stuff I'm reading, instead of just getting the major points and then remembering where to find it if I need more details. It's getting back down into the dirt again after being used to the high altitude overviews for the past 15 years.
The midterm was 20 long answer questions that covered more about polymers and ceramics than I studied for. It was basically two hours of dumping just about everything I could remember from the past 6 weeks of classes.
I don't think I completely bombed the exam, but I know I definitely could have done better.
