Eco major without math

I want to do an Eco major but I don’t have math in my senior year at high school. I got 1980 on my SATs. I also need financial aid. And again, I don’t have math. Will this prove to be an obstacle if I want to do an Eco major?

No it won’t! Your application is looked at holistically. It isn’t like the UK where there is a math requirement for certain majors.
Once in college, you’ll have to take introductory math classes which will cover what you need to know.
