Okay, so I know its late to answer this for 2008, but here's a tip for the future. Go Bold on the sections you are confident in. In fact, go bold unless you're really confused.

If you have a negative score, be a little more cautious. If you already have a -2 and you're not completely certain, go cautious.

I live by 2 rules:
1. Go BOLD or go home.
2. Above all, never get a negative score.
