I had an exam today in the afternoon but i was studying really late and i was really nervous but i decided to take a nap because i couldnt stay up nor was i thinking straight. Long story short, i slept through the exam and dont know what to do. Do i get a doctor's note? I heard about the freebie thing but im not sure if thats a real thing. does anyone know what i should do?

A doctor's note doesn't sound like it would apply to your situation.

I'd say your best bet is to be honest and ask them to defer it. The one deferred exam, no questions asked (within reason) does seem to be a real thing. They will hopefully understand that accidents happen.

If your record is otherwise good I would say you have a good chance of them granting a deferred exam. But, don't wait! Go in ASAP, send an email today and get in there ASAP tomorrow morning.
