Chances of transferring into Mays Business School at Texas A&M?

Can anyone help with specifics about what information to include/not include in transfer essay? I’ll have all required courses completed (with As in all required coursework) at the time of application. I want to transfer into TAMU-Mays. I know they are very selective with the students they choose, hence the reason I will have completed with As all required courses before application rather than in progress. ECON will be 2nd choice. What else do I need to discuss in my essay?
