I finally passed the .NET Applications mock core exam.
Next tests to go: ASP.NET, XML Web Services, Solution Architectures, and .NET Security.
One thing I hate about these tests is that they're 100% story problems that are hard to follow, and they have lots of problems that make you pick the best solution out of many working solutions.
I can't wait to get my MCSD. Once I get it, all my hard work the past year will be all worth it.
