Got my Scheduling Permit

I'm preparing for step 1, planning to give it in March, I received my scheduling permit from the ECFMG site, I want to know, will I receive the same in my postal address bcos its given in oasis, the status of my scheduling permit as sent on so and so date.
I received only a letter stating that my medical diploma s been sent to my medical school for verification and nothing more.

Is there a need for the medical school to sent the verified diploma b4 my exam? or can I write the exam with the scheduling permit which I got from ECFMG site ??????

plz help..........
