Hello Microfilter, I am currently in ground school stage 2 at oxford and whilst I havent failed any of my exams so far I do know a couple of students who have recieved the brush up courses. Both said that it was of great help in preparing them for the exams. Both of these students were intergrated but I have no doubt that it would also be offered to modular students too. Though hopefully with a little hard work you wont need them.
