Microsoft certifications can be rather tough sometimes, even when you're dealing with subject matter that you use every day.  In the current instance, I'm reviewing for exam 70-315, which is "Developing and Implementing Web Applications with Microsoft Visual C# .NET and Microsoft Visual Studio .NET".  Now, I'll admit that although I have been through C# training, my knowledge is a bit rusty - my focus at work has been on T-SQL, some Perl now and again, and a fair amount of scripting in various scripting languages, and I've neglected C#. Taking practice exams is showing me I'm woefully far from being ready to take the exam.  Yikes!  Well, I have a month to find some heads-down review time.  Wish me luck!
