Scratch Paper

You are permitted to do scratch work in the exam book on question pages, blank pages, or (for Level III only) the extra pages in the back of the essay book. You are not permitted to remove any pages from the exam book, including blank pages. Do not use your exam admission ticket as scratch paper. It is a CFA Institute testing policy violation to write on the front or back of your ticket at any time.
