  • Patent number: 6210171
    Abstract: An answer form for use in answering multiple-choice questions is configured to provide immediate feedback to an examinee as to whether a correct response has been made for each question, and if not, permits the examinee to proceed to determine the correct response. The multiple-choice test answer form provides for recording fill or partial credit for any response on the answer form, and is capable of being scored either manually or automatically by apparatus for form scoring. The answer form includes a substrate such as a paper surface upon which is printed a varying number of rows and columns of answer alternatives. The rows correspond to the questions to be answered, and the columns correspond to the number of answer alternatives for each question. Each alternative is covered by an opaque coating that can be rubbed off to reveal whether a particular alternative conceals an indication that the alternative is correct or not. A blank space beneath the opaque coating indicates an incorrect alternative.
