3. Get your marks in first
Another very popular strategy is to focus on the parts with 2 marks for a correct answer first before moving on to the rest: 4, 5, 6, 2, 3, 1, 7.
If you get most of the answers in parts 4, 5 and 6 right you are already on a very good way towards passing this exam paper. For example, parts 5 and 6 are worth 24 marks if you answer everything correctly. 24 marks is already a pass for the reading paper so you can leave parts 1 and 7 until the end and focus on Use of English.
If you start with part 4, which is probably one of the more difficult ones, you are still fresh. Get your marks, move to parts 5 and 6 and then to part 2 which is also a very difficult one. This strategy makes sure that you are focussed on the harder parts and the ones with a lot of marks.
