NYU LONDON: IELTS test to make a Tier 4 visa (UK)

Hello, I got accepted into NYU in London so I have to make a Tier 4 visa to goto UK.
And because i am not from European countries, i had to take IELTS test.
I can only get the visa once I obtain the suggested level or above. I have taken the IELTS on 11th of April, but I am considering retaking it, just in case i fail. However, if I retake the exam, its result will come out a few days after 1st of May, which is the deadline requested by the university.
I am just not sure if I will end up not going to UK because of submitting the IELTS scores a few days after the deadline.
Will the university let that happen? I have already paid for the deposit and the housing.
Thank you!

You have to accept your place, pay the deposit, and hope for the best. To be honest, if you do not pass IELTS, you’ll find NYU very difficult.
