ChemE and BiomedE have more premed overlap than EE or CompSci, so they are more advantageous in that sense. Disadvantage is the ChemE is the hardest major at any school, including OSU (it is dog hard). Doing premed anywhere in the College of Engineering is the hardest way to go premed because the mix of coursework is harder. The conventional Chem/Bio in Arts & Sciences is easier. A lot of engineering premeds switch to Arts & Sciences after freshman year after they figure that out.
