More and more students bring laptops, as it makes note-taking easier. It's great if you connect a microphone too, as you don't miss anything that way. Books generally aren't needed on the first day - that's more for discussions.
Actually, we've only had 1 true Chem lecture, and the homework due Friday has a ton of nomenclature stuff that we covered in AP Chem for weeks. So I'm sensing the tide closing in, which makes me prepared. My Intro Indian language class from the moment I walked in was a bombardment. One lecture and we've already learned the entire alphabet (a bunch of symbols that I somehow learned perfectly) and we had a quiz in which we made actual sentences with these symbols.
