Physics 1st, Chemistry 2nd, Biology 3rd, but what maths before physics?..please read..?

Question

My sister's in her first year of college. She tried to take biology, but on her 1st day, the teacher explained to the class that if they hadn't already taken chemistry, they would have a ruff time in her biology class. My sister dropped the class a week later due to complete confusion. She then attempted chemistry, but also ended up dropping out of it within the 1st week since she never took chemistry or physics in high school; and doesn't even understand what an atom is! Yes, the school system has failed her, what to do now? I found that physics, since it's the basis for understanding the more abstract concepts introduced in chemistry and biology, would be the best starting point for her. But, physics (along with all sciences) requires lots of math. My sister's taking college algebra right now. My question is, what math courses/subjects are recommended to take/learn before taking a college physics course (assuming no prior chemistry or biology courses have been taken)? thanks

P.S. Although i'm interested in a degree in physics and biology, this question isn't just using my sister as a cover for a question that's about me. lol She really is in this situation and I want to give her some sound advice.

Answer 1

Well, calculus is for sure the basis for physics. I think you could get by with without it but taking it would make an enormous difference. I agree with your train of thought about taking physics then chem then bio. Most high schools do the complete reverse of this which does not make any sense. Physics explains the basis of chemistry which explains the basis for biology. It seems thought that your sister will definitely have a difficult time in any of those classes if she didn't take any of these courses in high school. I am a freshman in college right now and am premed. I am currently taking my second semester of chemistry and my first semester of biology. I also took AP biology in high school and scored a 5 on the AP test so I already have knowledge of college biology. I would say for you that you will need to just jump in and take these courses. You won't have more time to prepare for these courses in college. That is what high school is for. You will just have to take them in college. Many science and prehealth majors in college have a very difficult time with the courses. It just takes a lot of studying and maybe a tutor. I would also recommend that maybe your sister should take some of these courses at a community college during the summer so that she could be more prepared and have a more solid background. That would make the courses easier.

Answer 2

I think college algebra should be fine for a basic physics course, and I can't think of any other prerequisites (so long as she's comfortable with the English language). I definitely wouldn't attempt it with anything less than college algebra. However, I don't think physics will help too much with chemistry unless you go several semesters deep. I think completing college algebra will be the greatest asset in chemistry.
