Does the college offer multivariable calculus, linear algebra, differential equations, and discrete math?
You have to check each school’s web site on transfer credit policies.
Obviously, that is a problem if you cannot attend the college and have exhausted your high school’s offerings. That makes the argument for early graduation stronger.
Community colleges are generally open admission schools which admit 100% of applicants. Does this community college have a significant population of students preparing to transfer to four year schools, and does it offer the frosh/soph level college courses to prepare those students to transfer to four year schools in a wide range of majors?
The OP may be an outlier in terms of being advanced in most subjects, while most of the student population at the school is considerably less advanced. The school may not have the resources to offer sufficiently advanced courses to very small numbers of students like the OP. (Also, the level is not that low, if the school offers calculus BC. Low level high schools may not even offer calculus at all, and have lower level math courses insufficient to prepare students for calculus.)
