nyu deferral

i got in to nyu andbi was supposed to start school this fall but i had to defer for some reason so now im starting in the spring. meanwhile i am planning to apply to cooper union early decision because i prefer cooper over nyu. the problem is, on the nyu deferral form it said i cant applt to any other school while i still have my spot at nyu and if i do and they find out they can reject me.
but i just dont see how they are going to know and even if therebis a way for them to know i dknt think they can until i get into cooper but then i wouldnt care about nyu anymore if i get into cooper
does anyone know any reason for me not to apply to cooper?

A desire to be honest and keep your agreement to NYU is one reason, but it sounds like that’s not what you’re asking (even though that’s what you wrote). It sounds like the real thrust of your question is “Can anyone think of a way I might get caught that I haven’t thought of.”

yes sure
can anyone?
