At Tufts, it varies from person to person. You will see a full range: people who don't do anything but listen during lectures, to people who take notes on their syllabi and/or powerpoints during class (myself), to people who tape-record and type everything at the same time. You'll figure out what works for you in a few weeks, but realize that it also may change from class to class, and/or what works for you this semester may not work next semester, so don't get too locked in to one style of note-taking.
FWIW, you get your syllabi before classes start, and they're pretty comprehensive. (I often found myself rewriting notes/syllabi because they were too disorganized for my learning style, not because they were lacking info.) Also, the PowerPoint presentations are almost religiously uploaded either before or during class, so you can take notes directly your file version of the presentation.
