I have a brother that also needs to fill his FAFSA form, is there a way to reuse some of our common info from my form to his?
Yes. At the end of the submitting process, you'll get a confirmation page and there you'll see an option for the parent information in your FAFSA form that you can use to transfer this information automatically into another student's application.
So we can also use an app?
Yes, you can find the 2020-21 and 2019-20 FAFSA forms on the myStudentAid app, available for android and IOS on their respective app stores.
