My rich custodial father is unwilling to pay anything for college. So, can I not include him in CSS?

I have a two friends whose dads wanted the. to be doctors. Neither did well in the premed coursework, so it became a moot point. Don’t know if they tanked intentionally, but it is possible. A well placed C or two in organic chem could do the trick. Not sure about the system in your country, though.
