I was the one who corrected it, but it was not online, they sent me the paper work and I had to mail it back.
The caveat is I did the correction, some other college came in and overwrote my data. There was no traceability on who did it, I called FAFSA and asked them how can they build a system where the college can change it and nobody can tell me who changed it. They asked me to call all 10 colleges and see who changed it, so I just called the one college where my child will go and asked them what they have on the file, it is a CSS school so I am safe that they have correct information.
My suggestion focus on the school where you will go and call them , if you think you will get more money from other colleges then call them. We do not qualify for any aid so there is no point in wasting my time to call each college.
