<p>At each school, look into whether is will be easy to switch into engineering if he starts out in chemistry. At Illinois, for example, chemistry is in the liberal arts and sciences college and the school of engineering is harder to gain admittance into as a freshman. I’m not sure how hard it would be to make a switch (minimum GPA, possibly?) but I would check at each of these schools so he would have an informed idea of what he would need to do in order to switch into engineering.</p>
