[Application Timeline] T5 MSCS, MSDS, MIS applications still open?

Hi,

I got accepted at my #1 choice in a very good university. Now I want to ask, if there are still applications open for MSCS, Data Science, Information Systems, Business Analytics at absolute totppers, as I didn't apply earlier since I never thought I'd get in? Only unis I'd still consider would be Stanford, MIT, Harvard, Princeton, Yale, Caltech. Rest would be a downgrade.
