I disagree with that. It appears that the OP needs to complete a FAFSA and apply for all financial aid available. The FAFSA requires the parents to provide their financial data, and financial aid opportunities are based on their income. If OP's parents refuse to provide their financial data for the FAFSA, then the OP can only file the FAFSA under very limited circumstances, such as if he's completely independent. However, if his parents claimed him on their taxes, then that claim seems to go out the window.
As for being a good writer, I just don't have the same faith that you do in what it takes to be in the top 15% of a high school class. When kids are being pushed through schools and graduating without being able to read and write anything (it really happens), I don't know why it's so hard to believe that a student could be in the top 15% of his class and yet have poor writing skills.
In any event, this topic seems dead, so I'm out.
