In my opinion, using someone else's notes, while probably not getting flagged at the test center, would most likely be useless to you. The single best review tool that you have, as the exam must be taken a minimum of 2 weeks after you took the class, is to create an outline of the course material listing page #'s and references. Going through and generating that table of contents, while it provides you with a quick lookup, is also going to help refresh your knowledge on those tools/skills. If after having made your own table of contents, you still have to look up everything, then realistically you shouldn't be trying to take the exam. Almost every certification exam I've taken in general has had questions on it that were so easy that if you don't know the answer, you shouldn't of even attempted certification as well as questions tough enough to provoke thought in experts. The second of the two types of questions are probably what you will end up needing to look up regardless just to make sure your understanding is correct (if you want a great score instead of just to pass), where making the table of contents helps is it will raise the bar for where your threshold is for having to go back to the book. Anyway.. just some thoughts.
