Any advice on Columbia's Post-Bac's "Cut-throat Nature"?


I’ve been accepted into Columbia’s program, but hav of professors really don’t advice/help students until the end of the program, and that there isn’t a communal nature among the program. To expand on the third problem, that post-bac students don’t interact with other students outside of class, and that there is an me verses everyone else mentality among the students.

Overall, I guess the complaints can be summed up as there is a high risk of failure in the program and some isolation if you don’t know anyone else in NY. Does anyone know this program well and can address the complaints?
