Exams 70-310 and 70-320

Developing XML Web Services and Server Components with
Microsoft Visual C# .NET
Microsoft Visual Basic .NET
and the Microsoft .NET Framework

These notes began with the "Skills Being Measured" on Microsoft's page for these exams as of June 3, 2002. Note that the skills for 70-320 are identical to the skills for 70-310. That's why Microsoft won't give you credit for passing both - it's really one exam that really requires no particular language expertise.

All hierarchically lettered and numbered items are directly from this MS list. Almost all links lead to http://msdn.microsoft.com online pages, a few more link to www.gotdotnet.com, and there are some that lead elsewhere. Here is some information about the evolution of links from local help files to msdn.microsoft.com, if you're particularly bored. 

The list is by no means complete or error free. Please if you find any additional links or ones that I've listed that are broken or irrelevant.

I took 70-320 on June 23, 2002. It seems like a relatively difficult MS exam, but does follow the topics listed pretty closely. I should know by the end of August whether I passed or not. I think I did, but am much less confident than I've been for most exams. My ritualistic self-scoring at the end of the exam predicted a score of 708.

I'm moving on for now to the 70-315 beta exam, which I'll take on July 7, 2002. I'll put similar notes for that one here.

I found out on August 2, 2002 that I passed 70-320 during the beta. I expect this also means it'll be going live shortly.

I took 70-310 on April 19, 2003. This finally completes my plan to take all of the C# and VB.Net exams, even though MS rightfully considers the exams redundant. Now I won't have to discuss that with any prospective customers, students, or employers. To prepare for this 'retake', I reviewed some of the links on this page, but also read the Microsoft Press Training Kit for 70-310 and 70-320. The book seemed like it wasn't going into nearly enough depth. It's a lot shorter than it appears - most code examples are repeated for both VB.Net and C#, and many of them also include boilerplate designer code that's conveniently hidden by default in VS.Net. I went through the included practice exam once. It 'sort of' lets you review your answers after you finish. The limitations all seem to relate to the glaringly bad user interface. Answer options aren't identified with letters or anything else, and the 'explanations' just seem to comment on the selection you made. So if you chose the wrong answer, it often would not tell you what the correct answer was.

While I still think the practice exam with the training kit is of low quality, the book itself may have been OK. This exam seemed much easier than I found the 70-320 beta. Part of that is because I'm smarter now than I was last June, but I suspect the beta process may have weeded out a lot of difficult questions. I don't think the 'retake' factor had much effect - I don't even remember what I had for dinner last night, and hadn't made any notes for myself after the 70-320 beta. There were a couple of questions that seemed familiar, but the overwhelming majority were effectively new to me.

I had 57 questions, 120 minutes to answer them, and predicted a score of 877 this time.
