I've wanted to apply for the kosen (I live in the US) but my embassy doesn't offer applications for it. I'm wondering if there's any other way to attend a kosen or if I would have to find another track under the MEXT?

hiyaa! I am a student from india in grade 11th. I am in humanities right now. How difficult is the maths written exam? Is it up to class 10th level or do i have to prep further bacause my worst subject is maths so im kinda scared ._.
