The IPN is a technical university, mathematics and physics are its pillar. The problem comes when teachers insist on having their students compete against each other; they don’t care about learning, but rather that there are some outstanding students. The workload is unhealthy, they never worry about your mental health, and they even make fun of you if you mention that you feel tired.
Along these same lines, they make fun of the humanities and feel superior for knowing, or half knowing, mathematics.
The facilities are very old, the buildings vibrate when heavy cars pass by. It’s not the best school.
