Wharton 2012 - Calling All Applicants

A high math percentile is EXPECTED from engineers or number crunching finance types. So in cases where such people fall out of that pattern, adcom starts questioning the applicant's professional qualities. At the same time, these applicants need to worry more about their verbal scores as in their case they are scrutinized more and give more insight into the balance in the initial skill set.

On the other hand, if your background did not involve much of the quant work engineers or equity analysts do, then it is EXPECTED that your verbal score should be in the high range. The focus then shifts to the Quant score, and the goal of the applicant then becomes mitigating the concerns the school may have about the ability of the applicant to handle the quantitative rigor of the program (and Wharton is often considered the most challenging top school from that perspective).

So here's where the 80/80 comes in: it is a universal solution, which eliminates the need to mitigate the GMAT component weaknesses in other parts of the application.

I would say that a higher math score will level the playing field for you at Wharton. Combine that with your UC Extension success, and you've got that part covered in full.
