Our exam prep tabs mark the specific sections of the book that are most often referenced in questions, helping you navigate the books quickly during the timed exams. You cannot use tabs such as post-its, as tabs must have permanent adhesive (per the exam proctor). Our permanent, pre-printed tabs are approved for use within the references for contractors' exams.
