One interesting thing in contrast to Berkeley. Here at CMU, regardless of whether you\’re an undergrad or grad, you always call your professors by their first names.

My dad bragged that when he was a TA, his students would call him Mr. Ng. Thankfully, such formalities don\’t translate across decades. Nowadays, we want to be closer to those who teach us, especially because now we\’re supposed to view them as human beings.
