I passed exam 70-320 today with a score of 904. This was the last exam I needed to get my MCSD.NET. In almost a carbon-copy of what happened in my 70-300 exam I forgot the exam was scheduled today because of a number of things going on, and only realized when I arrived at work. I had done a couple of days worth of study a month or so ago when I originally booked the exam. I finished the exam in about 1 hour.
