So, I thought it would be a good idea to write some posts on specific aspects of exam technique. Having marked many many exam questions over the years I am convinced that knowing what to do in the exam is just as important as revising information. Obviously you need to know the information first before you can apply it to the exam, but just revision alone is not enough for a top grade.Understanding command words is key. Even the simplest one can be misunderstood. Let's start with 'DESCRIBE'. This is one of the most straight forward things that you could be asked to do. However, many people make mistakes with this command word and end up losing easy marks.
