er's are useful as they give u tips on how to write ur ans so that it contains everything the examiner wants
it identifies common errors and make sure u dont make them to!!
as i said earlier, er's identify topics that were poorly answered by most so u shld focus on those as these have a high tendancy to come again
........one er went to the extent of saying that cyclones was a topic not known well and that it would b tested more in the future...that question turned up in my paper!!......if u read between the lines, ull b able to predict half the paper
