I passed on my first attempt - on December 30th. . You MUST know the formulas, but the math itself isn't difficult at all. The situational questions took way more brainwork and critical thinking. The Prepcast was a great resource for my preparation - especially the Exam simulator. Definitely worth the investment! I highly recommended the prepast tutorials and exam simulator for future test takers! I spent a lot of time taking practice tests to build up stamina and budget time and it really paid off on the exam date. The tutorials were easy to follow and very much helped in breaking down formulas and understanding the critical path method - all of which were covered on my exam.
