Why not take notes on paper and then, every night, summarize your notes on your computer? This will do two things for you - first, it forces you to go over the material again (something folks have shown helps for long term retention). Secondly, it gives you a chance to integrate your own notes with whatever resources the professor has made available online.
I had a grad student tell me once that the best way to study was to copy over all your notes after each class. And then, at the end of the week, summarize the week's worth of notes. At the end of two weeks, summarize the two weeks worth of notes, etc. By the time of the first test, you've gone over the material so many times already that you can reduce your study time. Plus, you have prepared a great summary with which you can study from (and if you are allowed to take in a sheet with notes on it, you've already created it). I've seen this sort of system work for many people (me, friends, other folks on my dorm floor). Clearly the advice was given before everyone in college had a notebook computer at their fingertips, but it would seem that it could be just as useful now. Especially if you don't copy and paste to create your summary, but actually type in the information anew.
Just something to think about.
