Myth or Fact!
It's a myth that US CPA Exam questions are from any particular book, any particular CPA Review Course or any particular software. On the examination day, you will not find questions from any of the CPA Review Courses or software. You need to have good knowledge and understanding of concepts. So, the rule to pass the CPA exam is not difficult to understand, "Focus on concepts not questions".
It is a myth that buying any CPA Review Course will make you a CPA in a few months. Any CPA Review Course that makes such a statement is doing this just to sell its product. No review course has a magic wand. You have to judge which CPA Review Course is giving you knowledge and understanding and which CPA Review Course is making you a fool.
