I am going to take CISM in the first quarter of 2018. I bought the study guide this year (15th edition)
Does a new guide come out every year? If so, does the content change enough on a yearly basis where you have to buy the latest manual to pass the test? Or should I be ok to use the 15th ed. Obviously, I dont want to study the 15th and then have to also read the 16th.
