Duke is strong in Business, Pre-law, Pre-med but no in Engineeri

I have a colleague who grew up in NC but went to Caltech for engineering. I asked him why he did not attend Duke. He said Duke is very weak in engineering except possibly BioEng. But definitely Duke is very strong in Business, Pre-law, and Pre-med (Tim Cook and another 2 top Apple executives are products of Duke and so is Melinda Gates).
