I didn’t say there was a special kind. I’m sure all kinds of students can do well there.
I just see CMU as very much a fit school. Of the several people I know who’ve attended over the years, some felt very much at home and loved their time there. Then there are several others who found it too intense and stressful and were miserable. And then there are those that loved CMU and hated Pittsburgh.
So, OP needs to figure out himself if he’ll enjoy being at CMU. Maybe yes, maybe no. Not for me to assess.
