ABSTRACT OF THE DISCLOSURE An electronically operable multiple-choice response evaluating apparatus. The apparatus comprises a relatively small and portable housing having a plurality of first input switches which are manually actuable by a user in order to introduce a code of indicia, as for example, a multiple-element alpha-numeric indicia, representative of a question. The housing also includes a plurality of second input switches which may be manually actuated by the user in order to introduce an indicia representative of a selected one of a plurality of possible answers for a question. The housing also includes electronic processing means, such as a microprocessor, which compares the code of indicia representative of the question with the indicia representative of the selected answer and makes an evaluation such as determining whether or not the user of the apparatus selected the one proper answer for that question. The apparatus may include one or more sheets having the questions listed thereon and with the identifying code of indicia for each question. In like manner, two or more answers may be provided on the sheet with each question, and again each answer will have indicia representing that particular answer. Thus, the user of the apparatus selects a question, uses the first input switches to introduce the code for that question, then selects the proper answer and uses the second input switch to introduce the indicia for that answer. A response mechanism, such as a pair of lights on the housing, will indicate whether or not the user selected the right answer. It is not necessary to have any physical interraction between the sheet and the housing in order to introduce answers and questions or to render a -1- determination that a correct answer has been selected. The code representative of the questions and the indicia representative of the answers are processed through an algorithm programmed into the processing means so that the relationship between the code of indicia for the question and the indicia for the answer are undiscernible to the user. Moreover, the memory capacity in the microprocessor can be relatively small since the same fixed mathematical procedure of comparing answer indicia with questions codes occurs for each question and all answers for each question.
