Perhaps a better question is:
Is your self esteem caught up in being smarter than a 5th grader?
I thought so.
Here's the test, anyway. I know you're going to take it. I did.
What did I get? Hmm, I scored a 90%. I guess I'm smarter than most 5th graders. It doesn't matter; I know I'm smarter than most college freshmen. See, I used a semi-colon correctly.
