Spend the first 2-3 minutes to read the passage as well as the bullet points.
Spend around 1-2 minutes to jot down notes for each bullet points. Try to get as much ideas in depth to gain extra marks. If possible, give some examples of your own.
For the remaining time, try to go through all the bullet points and contents you will mention later.
