Hi I have just passed 70-448 (MCTS: Microsoft SQL Server 2008, Business Intelligence Development and Maintenance). My preparation mainly consisted in the toolkit book from Microsoft Press, Practice tests (from Measure Up) that came with the book and Books online. I found this worked quite well and there were not too many "suprises" when it came to the Exam. Now the next step is to write 70-552 (MCITP: Desiging a Business Intelligence Infrastructure using Microsoft SQL Server 2008). In the preparation material on the MS site I see there is not toolkit book, no E Learnong and no practice tests. There are, however, three books mentioned: SQL Server 2009 RS Step by Step, MDX step by step and also in the learning portal there is mention of a third book "Smart Business Intelligence Solutions with Microsoft SQL Server 2008" and an E-Reference book: "Microsoft SQL Server 2008 Step by Step: Part Seven - Business Intelligence". By the way how does one get access to the E-reference book (the link takes you to a books24 site which seems to be subscription based. Anyway my question is what is the most effective way to prepare for the 70-452 exam? I dont mind buying the books (always good to have a good library of books) and I was hoping that like the toolkit for 70-448, there is an equivalent for 70-452 with a free set of practice test questions. I would welcome comments from anyone who has done both exams and can give me advice in prepararation. Thanks
