Abstract
An answer recording and score sheet device includes a markable sheet arrangement with at least one surface that has answer mark guide indicia. The guide indicia define sets of first positions at which marks can be selectively made by a respondent in response to corresponding questions. The sheet arrangement also has a surface on which a number of discriminable flag indicia are formed in a determined relation with respect to the first positions. The flag indicia serve to convey correct responses in accordance with a given test form or answer key, and are of such form as to enable rapid manual or electronic grading of the chosen responses.
