Yes. In fact, if you submit your FAFSA early, you may get a financial aid award letter sooner than later. With that information, you can make a better decision about where to go to school based on how much federal or state financial support you've garnered. Additionally, when you apply for outside/private scholarships at the local, regional, and national levels (which you should do regardless of your financial status or academic performance), those applications may ask for your FAFSA information, too. So, you'll be getting a headstart on any scholarships that may require it.
