Unless you change grade levels at the end of the spring semester (not years of enrollment, common misconception), or you are independent and have not taken out the maximum subsidized/unsubsidized mix for the fall and spring, no, you will not be eligible for additional federal loan for the summer against your 0708 eligibility. Depending on how your school treats summer enrollment, either as a trailer to 0708 or a header to 0809, a summer loan is considered part of the academic year eligibility. The question to ask is how is your aid divided during the year if you are required (not doing this as an option) to study in the summer. Ask your financial aid office.
