Is 4 years of math required / preferred for collage admission

Hello, Do colleges prefer or require that students do a math course in all four years in high school?

Depends.on the college. Most colleges list.the required/recommended HS classes on section C of the common data set and sometimes on their website as well. I’d recommend that you check each college you are considering applying to.

For transfer admission, any math requirements are typically stated in terms of college course work.

Obviously, if your major requires math higher than the college’s base math requirement for transfer admission, you will have to complete that math to transfer.

You’re in the transfer section, so, are you a transfer? If so, your high school record would later less than your college transcript.
If you’re in high school then you need to take math through precalculus or calculus or if those are too advanced, algebra2 or statistics.
