Help with appeal letter?

I am planning to appeal to USC. My reason for appeal is my family and financial circumstances. Is this a strong enough reason for appeal? I have written a draft and if you would like to help read it and give me advice, you can message me.
My stats:
Gpa 9-12: uw3.83, w4.31
Act:28 (did not send in 29)
10APs and 2 honors
~300hours of volunteer

Definitely Appeal! Don’t let anyone discourage you of appealing to your dream school. You will need to provide new compelling information that was not mentioned in your original application and you should mention your increase on your ACT scores as well as how you are fully taking advantage of your senior year. What has changed significantly since the time of the application? What did you fail to mention in your original application? DO NOT repeat anything that was part of the initial review. It needs to all be new information. Hope this helped out a little bit(:

Do you know when the last day to appeal is?
