Would adding this feature (similar to a small program) jeopardize the wp-31s's status as acceptable on college exams? On a recent post I heard that the calculator was deemed "Acceptable" on college exams because it has no "Program Memory" where students can tuck away formulas/answers to tricky exam questions. Any thoughts?
