Do you want to know how you can correct mistakes?
Yes, that's why I'm here.
Once your application has been processed, you can correct your FAFSA form online or on paper.
What if I accepted an offer for financial aid?
Then the financial aid staff at your college or career school will explain exactly how and when your aid will be paid out. They'll also tell you whether you need to fill out any more paperwork or meet other requirements.
Do you know someone who has forgotten their username and password? What would the process be like if I have entered some wrong information and I want to renew my FAFSA form?
No problem. Just Login into your account and select FAFSA renewal once there. It all will develop  automatically.
You mean i just sign in there after that, all i have to do is submit the form?
That's correct. Only log in, sign after you filled the form and submit.
Then, to resume, i just follow the instructions and then i'll be able to renew, right?
