I'm doing HEFC at Newcastle college as well, the full level 3 access course I'm doing (3 subjects and toolbox) is worth 60 ucas credits, 9 per unit and 6 for toolbox, but this isn't in the same grading bracket as A levels, which give more points but not on the same scale if you get me?
I think it'll be the same for you, 9 credits per unit and 6 for toolbox, but if you get distinctions in english it'll be "9 credits as distinction", same for merit and pass grade. So the amount of credits will be the same but at different grading, hope this helps.
If you need help with toolbox gimme a message.
