The exam paper recommends that you spend about 40 minutes on this question and this is about right. Remember that Task 2 gives more to your final writing band and so you should make sure that you have enough time after Task 1.
The exam paper recommends that you spend about 40 minutes on this question and this is about right. Remember that Task 2 gives more to your final writing band and so you should make sure that you have enough time after Task 1 to properly answer Task 2. Some students do Task 2 first in order to make sure that Task 2 is answered well before they get onto Task 1. There is no problem with this but make sure you write the 150 words to give a good answer for Task 1 as well.
So, whatever you decide to do about your approach to Task 1 and Task 2 in the writing paper, make sure that you spend approximately 20 minutes on Task 1 and 40 minutes on Task 2. This should give you the right amount of time to provide good answers to both tasks.
