Its not clear from your post if you are exempt from attending an approved course or not? If not you need to enrol with the likes of Bristol, Cabair, Oxford et al and they will provide you with a full set of notes. Then when it comes time to sitting the exams you attend a 2 week brush up course to prepare you and then you sit them at one of the CAA examination centres.
I would recommend Bristol whether you are exempt or not and when you are ready sign up to the Bristol database (50 quid for 3 months access) which you will give access to a question bank that looks remarkably similar to the real questions you will come across
Do a search on the above and read the sticky at the top of this forum to find out all you need to know.
