ABSTRACT:
A re-usable examination booklet for the administration of written tests includes overlaid question sheets bound together with the unbound edge of each sheet overlapping the underlying sheet. An answer sheet may be inserted in the booklet beneath the question sheets. Answer areas on the answer sheet are arranged in columns extending along the unbound edges of the question sheets to locate the answer areas in close proximity to the corresponding questions on the question sheets. A modified booklet includes question sheets having openings arranged in columns extending along their unbound edges so that the selected answers can be marked through the openings onto the answer areas of the answer sheet.
