My school does not require biology to be taken, and I would like advice about whether or not to take the AP Bio class. I plan to major in physics. I had previous planned to take Ap Physics 2, Aerospace Engineering, and Ap Bio next (senior) year, however I now plan to take calculus-based physics classes starting this summer. This may require losing one class (in addition to the space brought by Physics 2’s replacement), and I am not sure which class to remove: Aerospace or Ap bio. I have also considered replacing either aerospace or bio with guitar 2 and Ap Macroeconomics.
Colleges recommend (some may require) a credit of biology, physics, and chemistry. I would make room for some type of biology class.
Have you taken chemistry?
But I agree with @IrrationalPepsi, you should definitely take AP Bio. I’ve heard that it’s pretty difficult if you have no background, so review a lot during the summer.
I do not think @IrrationalPepsi said take AP Bio, but that some colleges may require a credit of. AP Bio is truly not required if you are going the physics route, though strong chemistry testing is. If there is no biology, which means you probably can graduate without four years of science (?), then, yes, the colleges will want to see that you have had the requisite four that your school provides, but not necessarily have bio on the line-up as one of them. Check the admissions requirements of places like UChicago, Embry-Riddle, and MIT, just to see what the ‘high school preparation’ suggestions and minimums are.
Most top colleges want to see at least one year each of bio, chem, and physics, regardless of level (regular, honors, AP), but prefer if you have taken them at a higher level. For some, this is highly recommended, but others, it’s a requirement.
Will you meet these requirements?
You don’t need to take AP Bio, but you DO need to have one year of Biology.
In fact, you need to have one year of Bio (regular/college prep/on-level, honors, accelerated, pre-AP), one year of chem (same thing: whatever level offered by your school), one year of physics, then one AP science if you can (AP Physics 1 or 2, or C if you’ve already taken AP physics 1 or 2 or got a high grade in Honors Physics; or AP Chem; or AP Bio; or, if you’re not as good in science, APES.)
Top colleges will also want to see Math up to calculus (or precalculus), Foreign Language Level 4 or AP, and 4 years of English and Social Science.
Aerospace is an elective, so it should be taken in addition to that, not in replacement. It sounds very specialized for High School.
If you’ve already taken Bio, Chem, Physics, and will take AP Physics, you’re fine taking Guitar2 and AP Econ.
Not sure if AP Bio is the way to go, but I would take at least one AP class. Try to have at least one class of physics, chemistry, and biology by the time you graduate college.
All the other classes I’m taking senior year are AP, and I’m taking 6 AP’s this year, so number of Ap’s is not a worry.
What science class did you take freshman year?
Integrated Science Honors (Required Class at my school)
I assume that Integrated Science Honors includes Biology, so you’re good. Essentially, the bio-chem-phys sequence means “the full, regular science HS sequence”. if the first year at your school isn’t called Biology, it’s okay. 
No, it was a general science course, I’m afraid. My school doesn’t have the normal sequence of classes, there are no required classes for the integrated science course. I’m not sure why this is so.
In any case, you have the regular sequence… Stop worrying about AP Bio.
It sounds like PLTW and the UW Madison classes are going to be more useful to you anyway.
Make sure you have Foreign Language up to level 4/AP and have 4 years each of English and Social science in addition to calc and college science, and you’re good
Okay, thanks for the advice. I’ve been told by some that they think most colleges prefer applicants to have a biology class, so I was concerned.
yes, but it’s in the sense of “bio, chem, phys”, ie., a three-year sequence in experimental science.
My previous post was missing some information, and I would like to get more informed opinions. My school does not require biology to be taken, and I would like advice about whether or not to take the AP Bio class. I plan to major in physics. Relevant classes: Last year I took Chemistry Honors and Astronomy, this year I am taking AP Chemistry, Ap Physics 1, and AP Calculus Ab. Next year I had planned to take Ap Calc BC, Ap Bio, Ap Physics 2, and Aerospace Engineering (a Project Lead the Way class). However, I have since learned that AP Physics 2 is not calculus-based, and so is not very useful. Instead my plan is to take physics courses at the UW Madison starting this summer. This may require the loss of another class in addition to the space created by the lack of Ap Physics 2, and so I am trying to decide whether or not to take Ap Biology. Bio is supposed to be a very work-heavy course, and if I will be taking college physics (along with other strenuous courses) I would prefer not to fill up my time with biology. I am aware that several colleges prefer a breadth of science courses, but I would like to know if it would be acceptable to not take a biology course, exchanging breadth for depth in physics and having already taking a courses in physics, chemistry, and earth science.
Most colleges require it. My high school, and I think my state, require it.
