Chemistry

So unfortunately this semester I am taking Chemistry... Small rant but why in the world is it required to have physics or chemistry for grad school CSD majors.. like WTF! As you can guess chemistry sucks!! I have a test tomorrow, and it sucks going into a test when you feel like no matter how hard you study and try on the test you are still going to come away with a B :/ The last test I did really bad on, and didn't even finish many parts of the test, so I have to do good this time! ? If only school could be a whole lot easier... lol
