- I give full examples where I show you how to answer problems, showing all working out.
- You will have a chance to work on practice examples with a timer – this will help you to get used to working with a time limit (a necessary skill for when you need to do tests and exams).
- I go through all the practice examples in detail after you have had time to complete them, so that you can see how you did – and where you went wrong if you made mistakes.
