Hello.. everybody
I want to download free lots of quiz papers of organic chemistry only.also multiple choice questions. CAN ANYONE PROVIDE ME A BEST SITE FOR DO IT?

This site is good, it also has tutorials and a message board so people on there will probably know some other sites as well.
Organic Chemistry Help! (http://www.chemhelper.com/)

I found quiz sites very useful when revising for my uni chemistry modules so I think it definitely is one of the best ways to learn this stuff. Otherwise it can be pretty easy to get bogged down.

Good luck!

Thanks... but I need downloadable quiz or question papers... with awnsers... think and help me again...
