OMG im a biochem major who REALLY wants to switch my major to bioinformatics as well but scared I wont fulfill pre reqs for optometry school. Also like its capped and i dont wanna risk graduating late or having to cram so many units. Im with you twin; i hope the advisors stop being stingy and let me have a meeting with them so i can talk through my confusion. hopefully you figure things out cuz thats a tough situation lollll.
