Federal Loans -- Accept or wait?

I just got offered federal loans by my school, in addition to the automatically accepted state scholarship. I accepted the subsidized loans, but I’m not sure if I’ll need all of the unsubsidized loans. I’m planning to take summer classes in 2019, so should I just wait until later to accept the extra money for summer? If I accept it for the fall and spring, will it be unavailable for summer or is that considered leftover unused money I am able to use for summer classes?

I would wait because the their is a limit on how much money you can get in the long run.

Wait and see if you will need it.
