It seems that they only open up at two main times every year, November and July. As it is July now, there seems to be lots of scholarships for high school seniors open for application now, so I passed the information on to my niece as I know she is in need of financial aid for college. It is really encouraging that there are so many options open to young people, after all, I think access to further education should be based on ability and not on how rich your family are!
Anyway I hope you find this resource useful, let me know if you successfully obtain any school grants.
