Yeah, I'm now thinking of using them as headers and using them as ideas to focus on and keep in mind. Another question I have which pertains to CHM1011 and BMS first year unit lab and tute classes is whether you'd prefer to have them back to back or not, and what happens during the classes since if I'm learning new content I'd like to review straight after. Also were the labs though especially CHM ones kind of hectic, and if I do have a lecture right after what's the chance of getting a seat in the front-middle rows, or is that not a worry because I'd heard classes usually end 5 minutes before the scheduled one.
In my experience for every lab I've ever done, they're not hectic, as long as you do the pre-reading. This typically just means doing all of the pre-lab questions (which for CHM at least, you had to do to even be allowed in the lab), and having read through the experiment beforehand so you know what you're doing. Also make sure you ask your demonstrator questions when you're unsure, otherwise you'll waste 10 minutes or more just second-guessing yourself instead of asking for help. I have, however, found them fairly draining, and wouldn't want to do them back to back - at the very least, I'd put a lunch break in the middle, if possible. Granted, all of my chem labs were four hours long - 1011 is three at max, and typically 2.5 if you get stuck into it, so you might be fine there.
It depends on the lecture on what your chances are for specific, but typically pretty good. It also helps a lot that most people want to sit as far back as possible.
