Econ/Acc Question!

So I completed all of the 5 pre-major courses that affect the major GPA and the other requirements as well. I received a C+ in both Econ 1&2, a B+ in Econ 10A, B in Econ 3A, and a B+ in Econ 3B. That calculates to a 2.84 GPA which is below the 2.85 requirement. Is my only option really to retake Econ 10A and get a better grade than a B+?

Since no one responded to this post, what happened? Did you appeal? What are you planning to do?

And how did you do well for Econ 10A? Just practice exams?
