I know. I'm a broken record. I'll shut up about the FAFSA when all of my students tell me they've completed it. For now though, mark your calendar for early February at the latest as the time you want your FAFSA complete. Remember, you can estimate and make adjustments later if you need to.
Now on to final applications. Get them in now! In addition to Federal aid, many colleges have campus based aid that is allocated in the coming weeks/months. You may be accepted based on a March application, but if these funds are already allocated, you're out of luck.
