WashU Olin Vs UMich LSA (potential ross transfer)

I contacted Ross to clarify and yes, they never had an opportunity to review my application, therefore I do have another shot at applying next year.
I think I could ace calc, but not so sure about economics. I’m currently in an IB econ course at my HS and don’t enjoy it, but would be willing to put in the work.
In your opinion, does the direct admit to WashU’s business school carry a significant enough advantage to justify it over potentially being stuck with LSA at Mich?
