I found the Met exam hard, definitely the worst of the lot. The RT practical was no walk in the park either. Like you I find the books pretty dull & got hold of the Oxford CD's from eBay. Best advice is stick with it & try to set yourself goals. Failing an exam is a bummer, it happened to me, just revise again & test yourself atleast 3 times on mock questions from the confuser until you are getting over 80% then have a crack at the exam. I've got my last exam soon, aircraft technical & it's a good feeling to get the ground school done, best of luck!
