AoPS Holidays

There are no classes May 29–31, July 3–5, September 4–6, October 31, November 22–28, and December 20–January 2.

This course was both the hardest and the most fun math class I have ever taken. I learned many problem-solving strategies that I hadn't been using before, and now, I feel one step closer to my AMC and AIME goals. Thanks a lot for this course!
