You can no longer use programmable calculators on physics tests at USC... Basically the test questions we're all versions of the homework problems with different numbers , I programed my old ti89 so I could just input the new values for the variables in the problem and out pops the answer. Tests took me about 10 mins perfect score each time, I showed a friend he told to many people and the following year you couldn't use programable calculators on physics tests anymore . They never said anything to me and I still got my A, if they had said anything I had my argument all ready to go, in that my major was Computer Engineering and this is what I'm supposed to do.. 😀
