Took me 14 months with Oxford - distance learning. I didn't feel that I was rushed, although I was working 12 hour days at the time so only had a few hours each evening to study - plus weekends. I actually studied in the office at weekends so felt like I never left the place!
I echo FFF's comments though - try to work hard to understand the material - you're going to need to use it one day and you're spending a lot of money for the course so you may as well get as much value out of it as you can.
