I purchased the CramSession as a last-minute study aid before my exam. While seemingly well organized, there are so many typographical errors that I stopped using it after the first few pages. Examples: On page 7, "Float" was listed as a primitive (it is not). On page 6, nearly a quarter of the reserved keywords are incorrectly capitalized! On page 10, "<==" is listed as a comparison operator (there is no such operator). I fear for the person who takes this information into the exam with them. This book needs a technical editor or a good proofreading.
