Am I suppose to solve all the general chemistry quizzes on chad's quizzes on course saver w/out a calculator? I'm getting the correct setup essentially every time but the math throws me off. It seems at some points the quizzes are tailored for the DAT w/out a calculator and then at particular sections it just gets out of hand with the answer choices if we were solely to calculate by hand. On a side note, will the answer choices on the DAT be distinct? As in if I calculate an answer, will it generally be the only answer choice in that range?
