I had 2 friends who 'broke up' Mod 1 and Mod 2 into a 4/4 and 3/3 but then wished they hadnt. Brush up is fantastic for the final push at getting you through the exams obviously at a point that you have sufficient knowledge , they bring it all together. Each to their own but i would try the 8 first as the overlap between subjects means that for instance Air Law and Ops are very very similar.
As Dick says post a question on the forum it is a gold mine of info from past and current students and no i don't work for them either i am a current student who believes the course/product they sell is second to none and very pleased i made the choice of BGS
