Hi everyone, I was wondering if anyone knew if the MCAT chemistry review books would be relevant/useful in studying for the Chemistry GRE Subject test? There don't seem to really be any books written for the chemistry subject exam, but the MCAT has review books for general chemistry, organic chemistry, etc. I wanted to know if anyone knew how the difficulties compared? Is the MCAT chemistry a lot easier than the chemistry subject test? Thanks!
