Financial aid offers will be posted for offered students on Monday. I'm not sure of the exact time. This can also be found on your student self-service page. Student Financial Services(SFS) has advanced a bit in that they will not send financial aid awards in the mail. You'll only be able to see them or any necessary documents requested online. I understand that they'll mail more information(payment plan, etc) in the summer after you have deposited.
In order to receive financial aid, you must fill out the FAFSA and the University Financial Aid Application(UFAA).
