SDN Members don't see this ad. (About Ads) Next Fall in order for me to get on track to start applying to schools next Year I need to take A Bio Course towards my minor, or Biochemistry. General Physics 1, and General Chemistry 2. I was wondering if any of you took three science classes and how did you do? Also I know it is ok in most cases to take 3 sciences classes with other core courses but is this a good idea.
