Not that bad.
Though the chapters could be longer and have more stuff happen in them.
It's till a good read.
Spoiler:
I especially like the closet pervert disciplinary prez. She may be a cliche character, but I enjoy every chapter she appears in. She's just so damn funny.
Maybe this thread should be moved to manga discussion though.
edit :
I agree with Jack. Childhood friend's mother is awesome.
