Awesome! The Brainbench C# Fundamentals exam just went public! Why do I care? Well, because I was the technical editor for the exam! I'm rather excited because this was my first publicly shown work as a technical editor of anything.
I think exam takers will find the exam to be fair. It's not too terribly advanced, but it's not a beginners exam either. It should really test if you know what you're talking about. One thing that I will remind everyone of is that C# is a standardized language, not "some Microsoft language". So, this exam tests your knowledge of the official C# (ECMA-334) language, not your slang usages of it. Also, sadly, this exam is on the older C# 1.0, not 2.0, which is my favorite language.
Currently the exam is available for free at brainbench.com. The full link is below. Enjoy!
