Same thing happened to me man, but mine was thankfully at the very end.

Shit that sucks OP I've done to countless times on 100+ question tests..

My freshman year of hs my biology teacher gave us a 150 q test, 149 answers where "A" and the 150th was "B". That test taught me to check often, which is this test for you. Fyl. :(

this is literally my worst nightmare. i have exams for the rest of the week.

It is my biggest fear. Especially for my biology class. I can't afford to mess up like that. Hopefully, you could get it sorted out. I know professors aren't always too nice about retaking important exams. FYL :/

I feel bad for you, that happen not only once to me but twice...

I do that all the time! It's ridiculous, I hate scantrons...

That's horrible! Speak to the prof. Hopefully they understand. Most of the ones I've ever met are pretty chill.

The fact you even spelled your username incorrectly say's a lot about you!

I hate when that happens!
