Challenge your mathematical problem solving skills with problems similar to those found on math contests such as the AMC 8, AMC 10, MATHCOUNTS, or the middle school math olympiads. I post a problem set each week, and then come back later in the week and post the answers and video solutions.

tis is really set is really good, it requires a lot of thinking!

I love these prob. hard and not boring

really interesting to follow your prob to prob.. nice, thanks for sharing..
