so i revised most of the weekend and quite intensively to sit a timed essay this afternoon. i sit down in the lab and read the question. and have no idea how im supposed to answer what they have asked. i do not remember covering this in my revision! possibly the worst ive felt over a piece of coursework since higher maths. luckily it is only worth about 2.5% of my overal grade so im not too worried. and at least the revision will be worthwhile for the exams in summer *sigh*
