Here's more evidence that the popularity of online courses is growing. Heisman Trophy winner Johnny Manziel, quarterback at Texas A&M University, is taking all his A&M classes online this semester. The San Antonio News-Express reports that Manziel is taking four online courses in sports management, which is his major. He says he signed up for an on-campus English class before deciding to go fully online. Aside from using the university's football facilities, Manziel is on the College Station campus about once a month, he says.
