Transcender Practice Exams - Transcender has long been a reputable source for providing accurate exams in Microsoft certification. The tradition continues as they offer practice exams for 70-630 and 70-631 (released earlier today). With each question, it offers an explanation of why that choice is correct and why the others are wrong. It also offers references to help expand your knowledge in that area. These practice exams are highly recommended and have proven very useful. Unfortunately, a company representative stated they will not be publishing practice exams for 70-541 or 70-542.
