I got 29.5/30 on my CS 2620 (Programming II) midterm. I have it autographed, framed, and sitting on my desk.

If you are talking about high school though, I got:
98% in Math (highest in school)
92% in Calculus
91% in Social Studies (highest diploma mark)
91% in English
89% in Chemistry (me and the chem teacher didn't get along)
86% in Physics (I was 1.5 hours late for the final)
79% in French 30 (Passed it in 2 days. Challenged the final)
75% in Biology (I never went to the last month of classes)
I'm sorry. I just had to brag for a minute considering my extraordinarily low GPA last year. (1.92)
