Jufarius,
The good thing about Creative Writing is that there is no cookie-cutter applicant. Most may have a background in English, but Philosophy is not such a far stretch. Take some English/Writing electives while you are at Yale to help beef up your transcript.
But really, the most important thing for a CW applicant is your portfolio. Write, keep writing, and hopefully by the time you apply for your MFA, you will have some good stuff ready to send out.
Good luck waa salaam,
AlHayat
