This forum is for information on obtaining Microsoft professional Certifications...if you wanted to know about the Certified .NET developer certification this is where you would post your questions on where to find training materials, and tests etc...
I'm assuming you want to ask technical questions relating to the Visual Basic language...and the forum linked above would be the place to do that :)
Hope this helps,
