My post is probably coming too late to be if use to you.
But, for future UM applicants in your position, here is my Class of 2023 daughter’s experience:
Her SAT was low, so she applied to LSA. She then applied for a cross-college transfer to engineering in September of her sophomore year. The deadline was Nov 1, and she heard in mid-November that her application was accepted. She applied with Calc 1, Calc 2, Orgo (she took the AP credit in Chem), Physics 1, and the required Comp Sci course. Her other courses were standard distribution requirements. She had all A’s except for an A- in the required writing course and a B in Physics, which she had not taken in high school.
Please consider this data, rather than information! We have no idea whether she cleared the admissions hurdle by a lot or a little.
