Adhesive-back question-bearing slips are taken from a teacher's file and affixed to a copy holder which consists of a back sheet to which the slips are adhesively attached, and a transparent cover or flap which folds downwardly from its upper margin over the back sheet, and which is imprinted with suitable heading data. The composite of back sheet, with attached question-bearing slips, and transparent fold-over part, constitutes a master copy which is inserted in a duplicator and reproduced in sufficient quantity to provide test sheets for all pupils of a class taking an examination, the heading data as well as the questions appearing on each test sheet. When duplication is completed, the copy holder is removed from the duplicator, the question slips are detached from the copy holder, and the slips are returned to the teacher's file for preservation for possible future use.
