hi, i'm singaporean and will be going to china to study for 7 months, where do i apply for student visa?

i have not been receive the acceptance letter from the school and i intend to go in august. do i have to wait for the school to accept me before i apply for the student visa? or do i have to apply for a tourist visa in Singapore first and apply for student visa when i'm in china?

also i intend to stay for another one to two months after my school term to tour around china, do i have to apply for tourist visa in china after the 7th month and request for extension up to 60 days?

thank you very much for your assistance and i look forward to your reply.
