Cambridge IELTS 15 Academic Writing Test 3 opens with a Task 1 process diagram and closes with a Task 2 discussion essay, so it stress-tests both data description and discursive argument in a single hour. Task 1 asks you to summarise how instant noodles are manufactured. Task 2 then turns to a discursive prompt: Some people say that advertising is extremely successful at persuading us to buy things.
Use the passive voice consistently and chain stages with sequencers like 'subsequently', 'once' and 'at this point' rather than counting 'firstly, secondly, thirdly'. Use two body paragraphs, one per view, then a balanced concluding paragraph that explains why both perspectives have merit. Use evaluative connectors — 'while it is true that', 'a stronger case can be made for' — to keep the discussion analytical rather than purely descriptive.
Keep Task 1 to twenty minutes by writing a one-sentence overview straight after the introduction; you can refine it during the review pass. For Task 2, plan for five minutes before you write — three minutes of planning here saves ten minutes of confused redrafting later. For band 7, vocabulary range and complex-sentence accuracy carry as much weight as the strength of the argument.
