Life at Wharton is a mixture of great fun and immensely hard work. With multiple parties, mixers, team-building events, and the formation of curated diverse learning teams, the school try to help its diverse student bodies intermingle and break the ice. The classes are interactive and one needs to be actively engaged in the classroom rather than a passive absorber of information. It is a great space for networking and forming lifelong bonds with new people from different corners of the globe.
First of all, believe in yourself. I met people from different backgrounds during my time at Wharton. Not all of them came from strategic consulting or investment banking background profiles. Everybody is given a chance to show if they deserve a chance at Wharton, whether they have a polytechnic background or a liberal arts one. Your skills, values, and desire to achieve something in life matter more than your background.
Secondly, do not underestimate the application process. The GMAT is less difficult than the application process. It is something you have never done before: analyzing and talking about yourself and trying to stand out without it sounding like a brag is very difficult.
The final advice is to get help from professionals from the MBA Center. The support from Dr. Hubert Silly was instrumental in helping me get through to the school I wanted to be in.
