This school is a joke and waste of students money. I've taken a few classes at Columbia and my experience has been very eye opening. The classes are interesting but the homework and exams are very poorly written by professors or TA who demonstrator their lack of understanding in certain subjects and complete ignorance in others. When confronted with proof of the correct answer they simple say you over thought the question. "Please remain ignorant like us".
I've found MIT to be much more challenging and driven to provide true understanding and knowledge.
I really feel sorry for students wasting their/parents money and receive a second rate education at an extremely high cost, not just in terms of money & money but at the expense of real knowledge.
Most of the reviews I've seen are by brainless idiots writing, reviews like " Great Wifi", "Beautiful campus, "I had a great weekend there"
Seriously, do your research before giving this school your time & money and risking your future.
