Cambridge IELTS 21 Academic Practice Test 1 Writing contains two tasks. Task 1 asks you to describe a line graph showing US jobs in manufacturing, retail, agriculture and healthcare between 1960 and 2020. Task 2 asks whether tall apartment blocks are the best way to provide enough homes in large cities. Write at least 150 words for Task 1 and 250 words for Task 2. You have 60 minutes, with Task 2 worth twice as much, before submitting both responses for evaluation.
