I think even I would strive to get my marks up if there were a threat to increase the school day by three hours ("Three city schools add 3 hours to day," Jan. 2). To "arbitrarily" increase the hours would probably rationalize my being so tired now that "I just can't get all this work done," and I'd probably do much worse. A continuous threat, however, might not only encourage me but entice my peers to blame me if the school day were increased. Just a thought!
