Well, the law had originally stated that everyone was only required 3 years of math, but then just last year they bumped it up to 4 years, but it didn't affect my particular class--the Class of 2011, that is--because we were juniors when they changed it, and I guess they didn't want the rule to have changed on us just when we may have been about to decide "no math for senior year!" hahaha XD
