Just a bit of advice about full time distance learning...
I know that this has been discussed before, but you have to be VERY motivated to work a 9-5 schedule of study if you are sat at home on your own. Depending on your subject, to think that you can sit there and do (e.g.) 6-7 good hours / day is unrealistic for many people. Your brain will just not absorb all of the info that well (esp. the more complex stuff)
I question anyone that says it can be done full time D/L in 6 (ish) months. Sure there are a few very motivated people out there who could do this, but on average I would leave yourself 7-9 months min. Maybe I am just a slow learner or a perfectionist. If you want to do it in 6 months, go full time residential / classroom where you have fellow students all around you to motivate you, to help you out or bounce something off the wall with you when you get stuck, and instructors who are physically present in front of you holding your attention.
Good luck..
