I dropped all unrequired math classes after my Sophomore year, because by the time I finished that year, I had fulfilled the amount of math credits needed to graduate (3).
I sort of regret doing that, as even though I find most math to be easy, it's very tedious, and I enjoy taking my time on problems. This was a problem when taking the SAT in May 2006, and the ACT in October 2006, and again in April 2007, as my knowledge of math slowly disappeared, and I only remembered basic things about high school math.
I THOUGHT that that would be the end of math for me when I made the decision, I had no idea that it was to be taken in college as well regardless of what major you chose. So, I feel like I'll be very unprepared the day I walk into a math class again next year.
