It’ll go fine don’t worry, follow the tips they send you
And try to select a topic that is interactive or add an element of interactivity onto your topic, always gets them interested
and Read your application thoroughly because atleast 1/2 alumni will go through your application in detail
And be confident of why you’ve made the choices (career, education etc) and why you felt it was the best for you
And why your choice was better than any of the alternatives that you could’ve chosen (this applied to post MBA career goals as well)
