Information for Owners of Previous Editions

Every new edition of the manual has the following changes from older editions:

  1. All errata as of the day of its release are incorporated.
  2. Coverage of topics may be expanded based on student reports from exams.
  3. Changes are continually made in response to student questions. When a student indicates that they didn't understand a solution to an exercise, I often expand that solution.
These types of changes are not available in supplements. Thus if you do not own an old edition of a manual, you may want to consider buying a new edition rather than a used one.

However, to the extent a syllabus has not changed, old editions should be adequate. Here is guidance to owners of old editions as to whether they need a supplement or a new manual:

  • For P, current edition is 2nd edition 2nd printing This edition incorporates material on the probability generating function, a topic that will be added to the syllabus for the September 2018 exam. You may continue to use any printing of the 1st edition if you plan to take Exam P before that date.

  • For IFM, current edition is 1st edition 2nd printing.

  • For LTAM, current edition for Fall 2018 is 1st edition 2nd printing.

  • For MAS-I, current edition for Fall 2018 is the 1st edition 2nd printing. The old Exam S manual covers much, but not all, of the material on this exam.

  • For C/4, current edition for Spring 2018 is 18th edition 3rd printing. This edition incorporates errata and the minor changes made starting with the June 2016 exam. If you are using the 17th edition, download this supplement for replacement pages. If you use the 15th and 16th editions, in addition to downloading that supplement, skip Anderson-Darling and for credibility keep in mind that the Mahler and Mahler-Dean study notes are the only available option, so study anything covered by those notes and skip anything not covered in those notes, as indicated in the manual. If you have an earlier edition, you should consider buying a new edition, since those editions do not include changes to the syllabus made in 2013.
