Many people have earned a degree in the evening after working a full time job all day. There are weekend courses also. Some schools run on trimesters with two summer sessions so it moves the process along at a quicker pace.
I'm not saying that all online courses are bad. I would just caution anyone facing the very high cost of a UOP degree to clearly define their goals and then ensure that the degree they earn will help them achieve those goals. If it doesn't then you just wasted a lot of time and money.
I know someone that earned her Masters at UOP but the company she worked for paid some of the cost and they guaranteed her a raise and promotion when she completed it. They made good on that promise so for her it was worth it. How that degree is viewed by other employers if she decides to change jobs is not certain but for now she made the right choice. She did her research, which is all I'm saying should be done.
