How many people can take a calculus class? The limit does not exist.

Calculus is a class that people take as a prerequisite for dozens of majors around campus and at colleges across the country. One course, titled Calculus One or Mooculus, functions as an introduction to calculus both for those who are new to the subject and those who just want to review concepts. So far, hundreds of thousands of people have taken part in the course on Coursera, an online-education website that partners with universities around the country, and more than 250,000 have participated through the OSU website, said Jim Fowler, an assistant professor in the Department of Mathematics. The YouTube channel also just recently surpassed 1 million views.
