Yes it's part time. I missed out my conditions for my first choice uni a couple of years ago and this year I applied to the same course again and they gave me an offer to just pass the open uni module I was doing. The module I did was 60 credits which is basically half of a first year at uni, 120 credit is one year, but if you do a whole year you can try and go into the 2nd year at a University if you want to. I live in England so I'm not sure about SAAS but I'm sure it will be fine.
