During high school I only took 2 sciences, Physics (honors) and Biology. My ability with science was pretty good, however it was a subject I had to stay awake in. My concern is not being a science wiz in High School will a 2 year post bacc, with literally all my classes being science based be too much for me. I plan on taking 3 classes per year with no job, so I will have a lot of time to dedicate to my books. Do you need a solid foundation in high school science to succeed with good marks (straight A's is the goal) in college? My biggest concern is getting in above my head, and it all ends up being a waste of time and money.
