There's an error on the first question - the correct answer is 3 (the one with the static Main()). When an option different than 1 is chosen, the error/info message (wrongly) says that the right answer is 1, but correctly displays the code from the answer 3.

BTW: you can re-do the test by deleting codeguru.com cookies (specifically, the one with the name "b2b_techIQ_CSharpBeginning").
