Will,
I think you get a seperate certificate when you pass each individual course. I have just completed my grammar course and my certificate for this will be with me in 2 weeks.
I read on here that you can ask for a certificate with all the courses and hours you have completed once you have finished all the courses you have paid for but i believe this costs £10 to do. Only going of what i read on another forum.
Hope this helps.
Nathan
