horrible sound during a misshift

I just finished my finals and felt hella good. There is this 90 degree bend that I always love to take. I fly around the turn and see a few squad cars in the local plaza. They look over and I panic. The freeway was about 300 feet away. I get to forth gear close to redline and threw it into 3rd instead and hear this horrible high pitch sound, scratching like sound coming from the engine area.

Any ideas on what it could have be?

I thought I might have smacked a valve, but the car still idles the same and runs fine.

…that’s your clutch…you scratched that’s all.
