Have you ever thought about doing a Master or MBA online? (Barcelona)

Hey there!

I just stumbled upon this link to the University of Phoenix:

The University of Phoenix offers a BA or Master Degree which you can do online in parallel to your job.

I wondered how many other re-known long distances studies are out there offering a graduate or post-graduate degree. Has anyone of you ever done any degree via an e-learning institute? Is it really effective? What are the advantages and disadvantages?

I am very busy with my day to day job but I have been thinking about starting a Masters Degree in parallel to my current job. An online course is a great alternative. Many of the big well known universities like Carnegie Mellon (USA), IE Business School (Spain) have started creating long distance courses as well. Seems to be a popular trend...
Would you recommend any others?

Looking forward to hearing about your opinions and experiences!

Have a great day,

Daniela
