or things that are out of your control?

I had a pathology exam a couple days ago (I'm a medical student) and I got 2-4 qs wrong, I won a scholarship and prizes last year so I have to be at the top and continue my legacy as number 1, but now it might be compromised.

I was talking to this guy after the exam and he got both of those questions right, the ones I fucked up. How do I cope with this?

I've been thinking nonstop about this failure I can't stop wtf is wrong with me? I want to win the pathology medal, might have to ace the upcoming exams but what if he does the same? I've only lost 4 marks out of 200 so far, maybe 5.
