You're right, analytical skills can't really be revised. I've done all the past papers/example papers available, as well as a few more my English Tutor made up by grabbing some random extracts. Still worries me though. Interestingly my answers ranged from about an A to a C... The A ones were ones in which I followed a specific plan that I set out a few pages earlier, the C ones were when I talked about context first, and tended to go off on a tangent. Much as I'd like to do more practice, I don't think doing any more past papers this close will help me, even if I can get them marked in time.
