It's not a matter of whether you can stomach Chem. It's a matter of whether you can do well in it. There are aspects of Pharm School I don't like but I adapt and move on. I believe Chem classes are weeder courses. Many people repeat them. You won't get into Med, Pharm, or Dental school with anything less than a B in your core science classes. IMO, it's about learning new concepts, understanding, and then applying them. Professional programs want people who can learn and understand new concepts. Just my 2 cents.
