When should I apply for student aid? I can't really get a straight answer from google.
Better late than never! ASAP
I would apply as soon as possible, so if you're a senior right now. I have researched too and cannot find a definitive answer, if you're focused on one specific college/university I would email them and their aid office.
To keep this community safe and supportive:
I would apply now. You might want to check the financial aid deadlines of the schools you are interested in. Also the FAFSA priority deadline is in the first part of March.
