An interactive self-test book has pages printed with sets of questions and
multiple choice answers and unique page identifying indicia of conductive
ink. A page recognition device is pivotable on a page support to bring
electrical contacts into and out of connection with the ink. A series of
question and answer buttons associated status and YES and NO lamps,
speaker, and total score display are mounted on the support for operation
by a processor. The score is increased for all questions correctly
answered at the first attempt for on any page. A correct second attempt
normally lights a YES lamp and emits a sound without increasing the
score. Results of prior attempts at any question are stored so that on
returning to a page, same YES lamps and NO lamps are relit permitting the
person to review and improve on the prior attempt.
