Farrah Abraham -- I'm Going Back to School!

Farrah Abraham has already used the Internet to peddle her porn video, but now TMZ has learned she's using the web for something productive ... to get a college degree.

Farrah has enrolled in Pace University (online) and is entering their Lubin School of Business in order to get a BBA in Business Studies. We're told the "Backdoor Teen Mom" star is concentrating in Accounting and Internal Auditing (we thought she was more into external).

Farrah tells TMZ she hopes to put the degree to good use ... she has plans to open a restaurant in the near future. She tells us, "I'm going back to further my education. It helps my future in terms of my business goals and secures a better future for my daughter."

Let's hope she isn't required to take any English classes (watch the video below and you'll see what we mean).
