Do it!
Are you looking to go to an onsite college or are you thinking about doing it online? I have done both and they have their pros and cons.
If your work-schedule or family responsibilities permit, I would suggest going to an actual facility. The face-to-face interaction and college experience is something you won't forget. If you cannot go to a facility, then do it online. I actually find that online courses are sometimes a bit harder as there is a lot of correspondence between the students and teachers. Since they can't see you, they really want to make sure you are getting all of the information, so a lot of work is given. Hard but worth it. You also have to be very disciplined, if you are bad at scheduling your time and are easily distracted, online courses are not recommended.
Because of my schedule, I am taking online courses. I did a lot of research before finally deciding which college to attend. The last thing you want is to spend your money and time and find out you went to a paper-mill school and not one that actually advances your career. Make sure it's an accredited college. Below is a website that reviews colleges based on student reviews.

I am "attending" Empire State College - State University of New York (SUNYSC). I am getting my degree in Business Management and Economics with a concentration in Human Resources. The online courses are challenging and the tuition is not too expensive. Check out their website:
