I was referring to your intellectual penis. Which is quite robust.
Jolie is creeping up on me.
Computers are more the norm, but some profs have started banning computers in the classroom, too. So it might depend. You will probably need a computer for exams, so you definitely need one... But there's nothing wrong with hand-written notes, just you'd probably have to transcribe everything later. Personally, I favor legal pads for notes -- I used them exclusively in grad school, and I used spirals in college.I type faster than I can write, so I would definitely use my computer for note-taking. I just hate having to transcribe and I would rather be able to organize everything on the computer for faster access.
Why are they necessary for exams?
