I'm a student in Pre-med looking to begin self-studying chemistry at a meticulous level. Since I've only recently graduated I haven't been too full on my course load, and I'm ready to change that immediately. However, as a student, I have no clue how I might choose great authors who give a comprehensive analysis of the subject, with poor ones who simply get you through exams. Up until now, I've been using the following books to assist me with my studies: Campbell's Biology: A foundation approach to the wonderful field. It's far from anything meticulous, but again it's supposed to give a general understanding of the subject. For a high-school textbook, it's served it's purpose beautifully. Zhumdal Chemistry: Again, it's only a high-school book, so It doesn't intend to serve as the forerunner of the subject. This is one of the authors I'm unsure about: It's explanations for electro-chemistry and Kinematics in general just felt too simplistic: Like It was neglecting something. So now that I'm ready to begin, I'm wondering: What books do you recommend for biochemistry and both organic/inorganic chemistry? I'm looking for calculus based books which provide a rich understanding of the subjects. My goal isn't to just pass exams, but to nurture a firm understanding of the subjects at a physical level. As for which books I'm looking at, I've had the following in mind: For Biochemistry I've been using: Lehninger- However I'm using the fifth edition that was a free-PDF, and it's age seems to show in a few places. So far i'm not sure whether or not I can say it's a good book, as I've only begun simple reviews, and integration of concepts I'm already familiar with. I've heard that for Organic/Inorganic chemistry, you would use Linus Pauling, but from what I've heard, the books on my level are more supplemental than comprehensive. Oxtoby or Atkins have been recommended to me, and I know that they're calculus based, so I'm leaning more towards them. Any help and recommendations would be greatly appreciated!
