Eve if you’re not eligible for more than one can you petition to become eligible, considering your advanced status?
You can reasonably hope to earn 3-4K if you work full time over te summer in a high-wage area; you can then try to earn 3K over the course of the year. So 7K, not 10K, would be your work earnings. (Note that as far as I know, they’d be taxed if you earn more than 6K)
You’d also get 5.5K in loans for freshman year.
It means you need to get full tuition and full ride scholarships.
