I think it depends on the school, ie., D1 or D3. Grades and good form will help a gymnast get into a D3. Of course you will need the great skills for the top D1's and they don't look at grades first. Stanford requires the same level of academic achievement as the average student there-for gymnasts (4+ GPA, 4-6 APs, 99% on test scores). They will dip down for football and basketball and they have a formula for those sports to meet a team average. A solid all arounder is someone scoring close to 9.5s on all events, at least getting 37s. Many awesome gymnasts though have one really strong event that can pull their AA score up, but they likely won't do AA in college if they are low 9s on an event.
