Why did I get the AP scores I know I didn’t deserve

I received my ap scores and they were way lower than what I believe I should have gotten. I took AP seminar and I got a 3 even though I knew I got well and should have got a 5. My IRR and IWA was amazing and my presentation was very good. I’m a strong writer but my ap scores just doesn’t make sense?

Is this karma for saying i’d get a 5 because I felt so confident in myself?
