Cheating is bad.

A point worth making also is that some of the questions are written very badly in poor English and are very vague. It takes some gearing up to naturally understand the style of questions (which relates to a one or two exam failures). Sometimes its enough to use some logical reasoning to get the write answer. You have a point about ms preferred answer. I've been building bi solutions since AS was released in 2000, experience doesn't always correlate with ms questions or how Ms intended the product to be used. When tabular was released we asked for guidance on use, upper limits of what it was capable of... basically we got no answers essentially because ms don't how it will be used yet or what its limitations are in real production applications.
