You can do either Summer Pi Challenge or Summer Pi Competition, but you can't sign up for both.
Summer Pi Challenge challenges you to memorize as many digits of π as you can this summer (from June 1 through August 31)! You will basically be challenging yourself.
If you decide on Summer Pi Competition, you will try to memorize the more digits of π this summer (from June 1 through August 31) than anyone else who enters this competition! There are two different classes, and winners and runner-uppers will be honorably mentioned. The winners will be privileged to have a post written about them all on this blog (Random Thoughts). Age will not be taken into consideration when the virtual ribbons are given out, unless a whole lot of people sign up in the same class for Summer Pi Competition. If that happens, we will award virtual ribbons for the different age divisions.
