Hi Tippy,
I am currently enrolled at Penn Foster College, and recently finished my first semester. I highly recommend PFC. The courses are challenging and you will definitely get an education if you apply yourself.
When you first enroll at PFC, they have you take two non-credit assessment tests in Reading Comprehension and Math. I was a total math moron in high school and I scored an 80 on the exam, so the tests are really nothing to be concerned about. They are just trying to determine whether you are capable of doing community college-level work.
If cost is a concern, the price is right at PFC. For my first semester I made monthly payments of $39. It's pretty hard to beat that deal for a quality education!
