How important is 4 years of math to colleges?

@ucbalumnus You are right about logistics, and I would add cost as a limiting factor as well. Nonetheless, I asked in pretty stark terms what the AOs preferred and that’s the answer they gave me - if you can, then you should.

@BooBooBear Sorry - Yes, my son may enter a STEM field, and I was responding to the OP who noted he wanted to major in engineering. I should have made that more clear that I was referring specifically to people like the OP who max out math at their school and want to enter STEM fields.
