Perhaps you are a poor learner...
Considering I walked out of my SS class with a respectable 75% which was about a good 20% higher than the class average (and I was like 3rd highest in my class) and I really wasn't there for about half the semester due to injuries (long story, not about to bore you), I'd say that's pretty damn good.
But to continue this topic on it's thread. I knew those 4, but I was half certain on about 3 others. Of course, half certain doesn't really help.
Although, it might be that I've been more concerned with my life lately to really learn about Current Events (hence my coming to this folder more often), so that would have something to do with it as well.
