The opposite sides of each sheet or leaf constitutes a page of the booklet and has printed thereon certain instructions or questions as well as so-called response areas or bubbles which are to be marked by the examinee. The various signatures are each printed with a sequence bar which collectively, if the correct number of signatures are properly inserted, form a recognizable pattern. If a signature is incorrectly inserted, duplicated or omitted, the pattern will be broken or will contain an extra sequence bar which apprises the inspector of faulty booklets.
