Option B is certified by the American Chemical Society. The ACS certification means that the program follows strict guidelines set by the ACS, including upper division lab courses, which conform to traditional industry standards. For more specific information about these different options consult with the chemistry advisers. Also the GPA requirement for the BS is higher, both for overall cumulative GPA and departmental minimum course grades. It is recommended that students who are interested in pursuing graduate level work in chemistry should pursue either one of the BS options.
Chemical engineers are also concerned with the economics of the scale-up process.
Chemical Engineering is a part of the College of Engineering and is a competitive admission department. I'm thinking of going to medical school. There is not a particular major that is recommended for medical school. The major that you choose should be something that you want to study. Due to the competitive nature of medical school admissions it is a good idea to choose a major that you can fall back on if medical school does not work out for one reason or another.
