Test update update: I got a 94 on my genetics test! Whoop!

The average was an 81, and my prof was super impressed. He said that he knew it wasn't because he was a good lecturer but because we'd studied really hard. And then he said that the rough letter grade distribution would be 83-100=A, 72-82=B, 62-72=C, etc...with the average being a B, this didn't make much sense to me...but I'll accept it! And he revealed that the final exam is optional. WHOOP!
