My personal experience is studying through my Chemistry GRE book and review and studying the crap outta that. Also, the questions on the chem GRE and the ACS exams are similar, at least in scope. As far as textbooks to study from, here is stuff that I found most pertinent...along with little mini reviews
1) Physical Chemistry, Atkins, the latest edition
-THE ULTIMATE PHYSICAL CHEMISTRY BOOK. Well, it's the one I primarily used as an undergraduate (for both PChem I and II). It helped out tremendously in reviewing thermodynamics, but the electrochemistry part wasnt really useful. The exam I took covered quantum, thermodynamics, and kinetics, so I give it a A on covering the latter two topics.
2) Quantum Chemistry, 5th Edition, Levine
-In addition to my own quantum chem notes from undergrad, this book (which we used in the grad lvl class) helped out tremendously on the grad placement exam. If you're going to be a hardcore physical chemist, use this..as for me..it's in my 'library'
1) Inorganic Chemistry 2nd edition, Miessler and Tarr
-One of the books we used in undergrad. Best part is that it's not thick and does a really good review of descriptive inorganic chemistry. I highly recommend the chapter on simple bonding models which totally helps out when reviewing for group theory. Also, it has one of the best explanation of 'isolobal' and the '18 electron rule' for organometallics. Totally helped out.
2) Inorganic Chemistry: Principles of Structure and Reactivity, 4th Edition, Huheey, Keiter and Keiter
-This is what I used in the grad level class as an undergrad and it has everything. It's the Atkins for inorganic, but it's thick and it's sooooo hard to trudge through by yourself. (The same can be said for Atkins). I recommend using the Miessler and Tarr for basic studying, and then using this book to go into more detail. These two work well together IMHO.
1) Organic Chemistry 5th Edition, Carey
-My undergrad textbook. LOVE it. Learn it. Even though I personally am not a fan of organic chemistry, going through the summaries at the end of each chapter totally helped me study for the placement exam. I prefer this one over the Brown and Foote. In addition, if you are pursuing organic for grad school, it really helps since your advanced organic texts are by Carey as well.
2) Organic Chemistry 4th Edition, Brown, Foote, and Iverson (previous versions just had Brown and Foote)
-What my friends used. They likedit for some reason. I looked through it, and going through Carey to this one is bleh.
That's all. I only had to take these three exams, so yeah..for those who have to take the Biochem ad Analytical Placement exams..what are y'alls thoughts?
