<p>To improve your CR mark, you should look at how you did on each different section of the CR, and each type of question etc.
For a lot of people (myself included) increasing your vocabulary helps A LOT. Try this link:

And if the passage-based reading is what brings your mark down, just keep practicing.
You could also improve your knowledge of literary devices, etc.
Hope that helps!
Good luck!</p>
