I did my first 8 exams in Feb and passed them all with LGU.
I took me about 7 months of distance learing to cover everything. I then spent about 6 weeks revising it all again, a few hours a day. I then went on the brush up course and got about 3000 feedback questions from LGU. Then spent a final 3 weeks doing nothing but feedback, past papers from the course with only very occasional reading from text books.
Feedback is the key I believe and most of the schools, certainly BGS/Oxford/LGU have got this weighed off now.
Good luck, it can be done.
