[trinitrotoluene]

Hi, I am currently studying some name reactions/rearrangements (Wolff, Claisen, Hoffman) and other pericyclic reactions. I wanted to know if anyone has a source for practice problems that I can use to study with. I know about the Dave Evans website, but I think I need a little more practice before I can solve those ones without having a brain aneurysm. Any suggestions would be great.

Thank you
