It sounds as if you are international. In the US, the majority of colleges require students to take a number of general education (GE) courses intended to give them a well rounded education. GE requirements will include a selection of history, language arts, fine arts, math and science. If you are a biology major, then the math and science you would take would be a higher level in order to fulfill requirements for your major. At UCSD, the university is so large that it is broken into 6 colleges, and each has a different set of GE requirements. You should look on line to find out what the required GE’s are for each college. You have to take those GE’s in order to graduate.
A side benefit of this system is that you may take a class outside of your major that you end up loving and wanting to explore that topic more. I know that at UCSD, my human biology major son ended up becoming a much better writer-something he used to dread- because of GE classes he had to take. If the GE system doesn’t appeal to you you might be better off not getting your education in the US.
