online tests

[segue]

What are some good resources for learning the details behind
recruiter type tests asp.net, C#, SqlServer. I've worked with .NET for
several years but these tests always challenge me - I have MCAD circa 2002
books.

Also regarding asp.net what are the pros and cons for using masterpage
architecture, skins, validator control, and repeater control, etc.?

Any suggestions/comments appreciated.

Thanks.
