Looking for Advice - Not sure what to do at all

I'm a college graduate and have an offer for IB from a reputable bank. I applied to a Masters in Finance program and have already secured housing and am reconsidering attending the program. I will note that I will not be able to start until February and have agreed to pay around $15k over the next year for housing. Was wondering if I could get people's advice on whether or not to drop out of the program and start in February or to attend and pay $50k and start in July. I have worked various jobs in the past and can afford to pay the $50k with minimal loans but am very hesitant to do so. If I forgo the program, I'm at a loss of $15k but will likely make it back with the income streaming coming in February. I will also say that the program I'm attending is not more prestigious than my undergrad. Thanks!
