advice before starting

So i'm starting on my paramedic science course come September and i honestly feel a bit lost now that i've finished college and have nothing to do.

So I was wondering if anyone has any advice to prepare for the upcoming year? anything you did or wished you'd done? I know many people recommend just spending the summer relaxing (and I will) but I would start feeling stagnant if I didn't have something to focus on

Thank you in advance!
