@Hell00 First, my niece was a bio major and applied and got into 5 different Vet Med schools (more competitive than pre-med). Secondly, the larger the school, generally the more weed out classes.
Union College as a small LAC gives you a leg up there. It has a strong reputation, ranked 44 in national LAC‘s. It does have a Greek system but USNews Compass reports that only 27% and 35% of the males and females participate in Greek life. IMO that is NOT heavily Greek. US News Compass also reports that only 15% of the students major in the biosciences and biomedical sciences making that seemingly a less competitive pool. Generally, the small LAC‘s have good retention Rates. Union‘s is 93%. It has a strong engineering program which IMO speaks to the overall rigor of the school. Look at the course catalogue and make sure there are enough bio science and neuroscience classes to have a strong and deep pre-med application. I would also recommend looking at it‘s internship placements in area hospitals. That will also be very important for med school.
That all said, high achievement at a larger university like Baylor, will speak loudly on a med school application. Baylor is also close to several large cities known for excellent hospitals. Again, I would inquire as to medical internship placements from Baylor.
