Wasn't sure what forum would be best for this question, but this seemed good since it was sort of more career related than homework. This August I'm going into grad school for chemistry at University of Southern Mississippi. When I arrive there, I have to take five ACS exams covering the five major areas of chemistry (physical, organic, inorganic, analytical, and biochemistry). So, I'm looking for study materials for those, ACS exams specifically. Anyone know where I can find free study material for ACS exams? I know there are study guides for each exam most likely that are for sale, but I'm trying to find something I don't have to order or spend money on. The obvious suggestion is just studying text book problems, but I'd like to familiarize myself with the ACS exam format, as I've only take one of the ACS tests before, which was the one for organic chem, and that was over a year ago. So, yeah, anyone familiar with the ACS exams and have any tips for preparing for them?
