Yesterday was the last day of school, and we told DS7 that his skip was approved to do third grade next year. When we got home he spent about the whole evening studying material he would miss in second (social studies only small gap there) but time will tell if he actually sticks with handwriting practice. All in all a very positive experience. Since the skip also places him into the full time TD program which doesn't start until third, anticipating he'll stay fired up.
