The library probably has the books (too late now; did you get them in time, get the math done?). The online class key is to do a lot of posting/talking, the "writing" will get stuff organized in your head and moving along in order. I always like to pretend it's kind of like checking my email? I go in the middle of the night and odd times to see who has posted what, and "work"/research on the Web at odd times and keep whatever is happening in the back of my mind at all times. Think of upcoming project thesis topics too and write opening paragraphs laying out what you're going to do and just add a bit to them as you go along also. I wasn't thrilled with the online reading, often printed that out or just scanned it and researched it in more detail on the web (so I'd make sure I covered the basic stuff it did). Constantly ask yourself the key questions and answer them, tie things together.
