I assume you mean the TA Level 3 diploma course with the 9 assignments and the final exam. I just passed my exam with a distinction, but the actual exam took me months to do. I wasn't sure what bits to summarise, so I summarised the whole of each of the 9 assignments. I sent in 93 pages, but I did get a distinction. I know some people sent in a lot less, but when I rang up the person I spoke to told me that if I left some parts out I would lose marks, so I just summarised everything!
