How many essays are too many???
Back in October of 2009 I decided that a good way to study would be to write essays (or at least good outlines) for every exam question asked on the theory paper for the last 10 years. The logic being that there was very little chance that the majority of the MW theory exam would be made up of questions from different topics than have been covered over that time span and I would have prepared at least one or more ways to answer them by the time I sat the exam.
