Are there any good sites where we can test our testing skills?
Sites containing Questions, Quizes on Manual testing, QTP / LR , PL/SQL skills?
Sites to Test the Tester? Never heard of them...but would this be any different than volunteering for an Open Source project or joining some Crowd Test site?
Nothing learns better than experience.

Cem Kaner has open-sourced his college courses on testing here: http://www.testingeducation.org/BBST/index.html
If you want guided instruction through this same material with a certificate for passing, you can take these courses online through AST.
