Regardless of whether or where Columbia is ranked, I’ll continue to put them in my “CCCP” group –
Caltech
Chicago
Columbia
Penn
hehe
So you have HYPSM, followed by CCCP.
To make this somehow useful to some kid reading this, if you get into a school from the HYPSM group, and a school from the CCCP group, choose based on fit and cost. Disregard any perceived difference in prestige – they are all prestigious at that level, and you can go anywhere you want to go from any of those schools, if you are willing to put in the work and shake some hands.
