general

I have QUE books for actual hands-on studying at home. But I wanted books for a quick on-the-go studying. I'm satisfied with the sets for the following reasons:
1) each book is light enough for me to carry in my backpack everyday.
2) Content may not be in-depth but is decent enough.
3) Exam questions are much better than QUE books. This is arguable However I just passed 70-315 and I can tell you that many of the questions were awefully familar thanks to the practice questions that came with the set.

No discount code in my set but I bought the voucher from online companies that offers 10+ % discount.

This set is a great deal when it comes with the vouchers, but still an OK deal otherwise. The books for the Windows, Web, and Web Services exams are good and they were able, with no other material, to allow me to pass those three exams. The book for the Solution Architecture exam (70-300), however, is useful only as a paperweight. That book is so poorly written, I couldn't even finish half of it! Fortunately, Exam Cram 2 has an excellent book for that exam. Not only is this set cheaper than buying the three good books separately, but the paperback editions in the set are lighter and smaller as well.

This kit is a great way to reinforce what you THINK you know and to learn new things. I'm not concerned like some of the other reviewers that the materials are not great for test cramming--these books helped give me confidence to pass the tests because I know the stuff cold! And I've passed the two Core C# tests, each the first time! Thanks Microsoft Press!
