Reddit mentions of Biochemistry For Dummies

There actually is a Biochemistry For Dummies book, and it's pretty good. If you don't need the detail of Lehninger you might consider it.

Biochemistry was absolutely terrible. That was the hardest I worked in undergrad and the happiest I ever was to receive a passing grade. We had a similar set up where there were three or four tests and that made up the entirety of the grade for the class. Just to reiterate what others have said: CASPA will average the two grades. No way around that. Don't let that get you down though. Do well when you retake the class and do well in your other science classes and it should be fine. I would definitely look at taking other high level biology classes to demonstrate you can do well in higher level academics. Biochemistry for Dummies was actually really helpful. https://www.amazon.com/Biochemistry-Dummies-John-T-Moore/dp/1118021746 Khan Academy was also really helpful. They don't have a biochemistry topic but they do have a section for MCAT prep which covers a lot of the topics presented in biochemistry. https://www.khanacademy.org/test-prep/mcat/biomolecules

I had to withdraw from A&P and had to retake a psych class. Nothing was mentioned about my grades during my interview for PA school. Best of luck to you.

• [Introduction to Human Nutrition] (https://www.amazon.com/dp/1405168072/ref=rdr_ext_sb_ti_hist_1) is a very good book to get started with if you have a solid biochemical background
  
  
• If you need to get some knowledge about biochemistry first I recommend reading Biochemistry for Dummies which is ok for non-professionals to read. One of the best Biochemistry books is Lehninger, Biochemistry, but it is very pricey
  
  Nutrition is mostly about biochemistry. So I'd recommend you reading some biochemistry books instead of nutrition based ones. Once you have a solid knowledge of biochemistry you'll be able to understand nutrition without a problem.
