  Marking C3 Coursework
  
  C3 coursework is very prescriptive. Providing assessors follow the criteria carefully there is no problem with the assessment. However, there are difficulties for the External moderator.
  
  â¢ Errors are made in the marking â¢ Work is not checked but assumed to be correct. â¢ Credit is given for work that is not evident.
  
  It is not a question of "what is a good piece of coursework?" but "how can I ensure that I give an appropriate mark?" 1 Terminology This task is all about solving equations. Therefore, candidates should write equations. Persistent errors should be penalised in domain 5. Examples which should be penalised: I am going to solve the equation x3 â 4x â 1. I am going to solve the equation y = x3 â 4x â 1. I am going to solve the equation f(x) = x3 â 4x â 1. Correct terminology: I am going to solve the equation x3 â 4x â 1 = 0. Or I am going to solve the equation f(x) = 0 where f(x) = x3 â 4x â 1. 2 Illustrations All three methods require a graph and an illustration for both success and failure. A graph of the function is not an illustration of the method. Example I am going to solve the equation x3 â 4x â 1 = 0 Here is a graph of y = x3 â 4x â 1.

  You can see from the graph that there is a root of the equation in the range [1,2] which I shall find. This is not enough - only the graph has been drawn.
