Want to submit your FAFSA to more than six schools? Here's what you do according to FAFSA:
Submit your application with the first six schools listed. After your application is processed and you receive your Student Aid Report (SAR), go to the FAFSA on the Web home page and select "Make Corrections to a Processed Application" under the FAFSA Follow-up sections. Add up to six additional schoools on your application.
Note: You may have to remove some schools from your application to add new ones.http://www.fafsa.ed.gov/faq014.htm#faq014_5
