The fact is that, going by the rules, you do not qualify even as a fee paying student. Th reason is that interscience is required for BSc Administration and you had e8 in interscience. To replace interscience with social studies, you need to have at least c6 in interscience before we can replace it with social studies.
Fortunately for you, we live in a flexible world where anything is possible. Although officially you do not qualify, If you have the money, yous should still apply because the school can make exceptions for you as a fee paying applicant. Every school needs money and fee paying students give the schools a lot of money so please proceed to apply knowing full well what might happen.
