Id have to agree, I didn't study before hand. Honestly, I didn't study much outside of the class room maybe an extra hour a day after class. They keep you there from 8-4 everyday (sometimes earlier). The student notes they give you I found to be useless. Do yourself a favor and print out the systems manual. I studied that before every exam and did just fine. It explains things a lot better than their notes. However, they were trying to fix those when I went through so im not sure if they are any better now. Start studying limits after indoc, get ahead of the game. You will appreciate that one later.
