Hi Craig
I have just completed the access but mine wasn't for social work, my college only offered the access to health proffessions over the part time route which is the route i needed to go down. i am actually starting the degree in social work in september.
All i can tell you about my course is we studied psychology, sociology and some english along with a lot of human physiology!!
but as far as i am aware each college is different with what they offer
good luck sorry i cannot help further.
