I’m an international student(Indian to be precise). I’m finding the high school course requirement criteria for US colleges a tad bit confusing. I’ve come to see that most colleges require 3 years of maths in high school(at least the ones that I’m interested in).
Does this mean that I need math in my 10, 11 and 12th standard?
This bothers me since I’ve not taken any maths courses in my 11 and 12 std. I had maths till 10th standard.
Here’s all the subjects I’ve taken(in 11th and 12th):
Physics, Chemistry, Biology, Information Technology, English, Environmental Studies and Psychology.
And all the subjects I had 8-10th std:
Maths, Physics, Chemistry, Biology, English, Social Studies, Hindi, Information Technology.
Will I not be allowed admission in US colleges? This is really bothering me.
You took more science classes than math? 
@NASA2014 Yeah. I didn’t really think ahead and just took courses that I liked. Kinda regret it now.
This will really depend on the colleges targeted; many list their suggested HS preparation on their websites. The majority of applicants to highly selective colleges will have had math through calculus. Even the non-STEM applicants will generally have taken at least precalc. If that is not your preparation, you would be at a disadvantage.
@skieurope would physics and chemistry courses that include calculus satisfy the calculus requirement?
I said nothing about a calculus requirement. Few schools have calculus as a requirement, although there are exception. What I said was that most applicants would have taken calculus. But no, physics with calculus does not replace calculus.
Having said that, if you are following a curriculum that narrows your subject choices as you progress, (e.g. similar to the British standard), colleges are aware of that, and will take that into consideration.
You are an international applicant who has been studying outside the US. You will not be expected to have exactly the same courses as a student educated in the US.
It is perfectly OK for you to contact the international admissions office at each college and university on your list, and ask them about your courses. You also should get in contact with the counselors at the closest advising center of EducationUSA. The whole purpose of that not-for-profit organization is to help students find good places to study in the US. The counselors will be able to help you understand how your coursework fits the admissions requirements of the places on your list. https://educationusa.state.gov/find-advising-center
@skieurope @happymomof1 thanks for the advice. I’m really grateful! I’ll get in contact with the admissions office as soon as possible
what math have you actually had? In the US traditionally 9th grade was Algebra 1, 10th Geometry, 11th Algebra 2, 12th Trig and Pre-Calculus. Many students who are applying to selective universities start high school level math sooner so that they take Calculus junior (rarely) or senior (more often) year. Calculus is offered at different levels depending on the school and may be stretched out over two years. It’s quite possible you’ve taken more math than you think you have.
As others have said, American colleges are aware that international curriculum may not line up exactly with what a typical American high school offers.
You’ll be expected to have had up to precalculus. Whether you completed it in 10th grade or 12th grade doesn’t matter. Completing Calculus is better if you intend to study science/math, obviously.
What curriculum are you following? CBSE? GCSE/OLevel/ALevel?
Calculus is done and dusted by year 10 in the GCSE system, lol.
No, GCSE math has two tiers, none of which include calculus. The current top tier include some precalculus and students who sit “advanced entry” to prepare for Further Maths have Precalculus but Foundation students don’t.
Even with the GCSE content change starting this Steptember, which is seen as much more rigorous than the GCSE maths as was taken until now, the higher tiers include stuff like Quadratic Equation, triangle sine/cosine rules, quadratic inequalities, sketch y=tan x… The top content for the Higher tier will include solid precalculus and will not include calculus.
