I did it because my daughter asked me to. She was 16 and I was following all the advice online (including CC) that students should make all contact with the school. It was just too much for her. It started even before the FAFSA because she was a recruited athlete and we were juggling athletic aid with merit aid and some state funds. She just looked at me and said “Would you deal with this?” The coach at the school she ended up at was new so she didn’t really understand the school’s merit awards or state grants.
Other kid is no good at math and just lets me do it. I had her do it one summer and she missed a deadline and it cost her (not me) $2000.
I’m pretty good at it and enjoy it, so why not? I also did their taxes and really, there was no way they could do them as their taxes depended on mine and my depended on theirs. They were also in school in April when I was doing them. I’d do them, call each kid and say “I’m going to push the button” and they’d say okay.
