No idea the answer but I feel your frustration. My kid took Chemistry at GT when he entered as an ME and got an 89.8. Not rounded and he ended up with a B/3.0 in that class. He is still irritated about it, particularly now since he is IE and it is not needed for his major. Talk to the med school advisor. My expectation is it is very common at GT and GT kids do place well in in state med schools.
Also BME is probably the hardest major you can take at GT if you are med school bound as it has among the lowest GPAs. The best hack for med school admission is to get great grades in pre med classes and major in something easy - my physician sister chose her major based on what the football players were majoring in (psychology at her college).
