ABSTRACT OF THE DISCLOSURE Educational apparatus which comprises a plate divided by a grid of ridges into a number of discrete areas representing possible answer zones. A sheet of paper has corresponding zones on it so that a student can select answers by punching the paper with a stylus. Only certain of the discrete areas on the plate have sufficient depth to allow the stylus to penetrate the paper to a substantial extent. Each of the ridges has a peak and a pair of ramps on opposite sides of the peak to guide the stylus into the recessed areas, thus eliminating non-response space.
