Is econ B.S. a hard major at UMD?

I was a former UMD second year student until I flunked out because I was doing comp sci and failed that entire major. I transferred to a local community college where I took the first 2 beginner econ classes there and passed. I am now transferring back to UMD to declare a econ major but wondering for those who are upper level econ majors if it is hard? I was thinking of pursuing a B.A. in economics, however, since I have already took calculus 1 and 2 (regular calc not business calc), I am qualify to enter the B.S. route
