My highschool chemistry class required us to memorize that stuff, but they also let us use graphing calculators on every test... Memorizing it still pays off because it saves time, but I think a load of students didn't bother and just 'cheated.'
(I'm not really convinced this is truly a form of cheating since if you look up the answer frequently enough you'll end up memorizing it by accident anyway. You can only look up Pb so many times before you start to remember it means lead.)
