It isn't, the parent probably just didnt know the name of the course being taught (or didn't reference). I'm a current UChicago Booth student. My bet is that the parent poster was auditing a class of Building the New Venture. The following classes are Entrepreneurship or Venture Capital focused (in no particular order):

  Building the New Venture
  Entrepreneurial Finance and Private Equity
  New Venture Strategy
  New Enterprise and Small Business Management
  Special Topics in Entrepreneurship: New Venture Challenge
  Entrepreneurial Internship Seminar
  Commercializing Innovation
  Social Entrepreneurship
  Entrepreneurial Selling
  New Venture and Small Enterprise Lab
  Private Equity/Venture Capital Lab
  International Entrepreneurship Lab - China
  E-Business Technology
  Developing New Products and Services
  Laboratory in New Product and Strategy Development I
  Technology Strategy
  Designing and Leading the Entrepreneurial Firm
  Statistical Insight into Marketing Consulting and Entrepreneurship
  Innovation in Energy Markets and Opportunities in Renewable Energy
  Structuring Venture Capital, Private Equity, and Entrepreneurial Transactions

You'll note that many of those are Lab classes - meaning that we work with real companies/firms on real issues they are dealing with. I'm likely missing 2-3 classes.

One of the people responding to the parent noted about how different the UChicago method is: focus on real data, real experience, and hard analysis. I'd say at least 30% of our class has some sort of hard math/science/engineering background.
