Dear Senior,
In case you haven't looked at any of my other pages and observed my love of the Art of Problem Solving website, click here to learn more about the website and its intentions (make sure to scroll down). My last tip mentioned taking the AMC for various reasons. Well, for those same reasons, I recommend you look at some of the forums on the AoPS website. They have any form of competition math you could ask for, and as I said yesterday, this kind of math will help your thinking quite a bit–more than you'd expect.
Best of luck,
-The Online Counselor
