Cambridge IELTS 21 is testing task completion, not a new template
Cambridge IELTS 21 does not support a sensible prediction that one Writing question type is taking over. Its four Academic Task 1 questions deliberately spread across a line graph, plans, a process diagram, and a chart-and-table combination. Its four Task 2 questions also require four different response structures.
The stronger pattern appears in the examiner comments. Every published Task 1 sample is criticised for a missing, incomplete, or overly general overview. In Task 2, even the 7 and 7.5 samples leave marks available when they do not engage closely enough with words such as ‘best’, under-develop one required branch, or let paragraphing and linking become mechanical.
That leads to one practical conclusion: do not use Cambridge IELTS 21 to guess the next topic. Use it to practise recognising the exact job hidden inside each prompt, then make every paragraph serve that job.

The scores below belong to the candidate samples selected for the book. They are teaching examples, not a claim that Task 1 is generally harder than Task 2.

Task 1: the overview is the threshold skill
The four visuals look unrelated, but the examiner response is remarkably consistent. Test 1 includes a closing summary that is too generic and misses the manufacturing peak. Test 2 reports the café changes but provides no overview. Test 3 describes parts of the rain-shadow process without summarising the complete transformation. Test 4 attempts an overview but fails to cover both the chart and the table.
This is more specific than the advice to ‘always write an overview’. A usable overview must compress the visual into its organising idea: opposing trends in a line graph, the dominant redesign in plans, the full cause-and-effect chain in a process, or the leading user group and strongest satisfaction contrast across a combined visual.
The lesson is stable across formats: before selecting details, decide what the whole visual is mainly showing. If that sentence is vague, the body paragraphs will usually become a list.
Task 2: the decisive words are inside the question
The topics are familiar—housing, entertainment, university experience, and primary education. The difficulty comes from the scope attached to each topic.
High-rise housing in large cities
The response must do this: Evaluate the claim that this is the best solution, not merely a useful one.
Online entertainment and physical venues
The response must do this: Address both views and keep the economic and cultural arguments distinct.
Study abroad or work placements
The response must do this: Compare the two sides and account for both forms of compulsory experience.
Formal learning and play in primary school
The response must do this: Answer both questions directly instead of turning them into one general education essay.
This is why a memorised topic essay can sound fluent and still lose Task Response marks. A housing essay that never tests the phrase ‘best way’ has not fully answered Test 1. A balanced essay that lists advantages and disadvantages without deciding which side carries more weight has not completed Test 3.
The stronger samples show that clear ideas and varied language matter, but they do not cancel an incomplete task. Cambridge IELTS 21 keeps rewarding relevance first: a direct position, development that matches every required branch, and a conclusion that returns to the actual question.
The trend in one sentence: move from templates to task control
Cambridge IELTS 21 does not introduce a new scoring system. It makes an old scoring principle unusually visible: language is judged through the work it performs. An advanced phrase cannot replace a Task 1 overview, and a polished four-paragraph structure cannot replace an answer to every part of a Task 2 prompt.
For 2026 preparation, broad topic prediction is therefore a weaker use of this book than deliberate task control. The transferable skill is being able to read an unfamiliar prompt, state its central job in one sentence, and keep the response aligned with that sentence under time pressure.
A focused way to practise the four tests
Use the tests as a sequence. The aim is not to produce eight polished answers immediately, but to make task completion automatic.
Three passes
- First pass: for each Task 1, write only the introduction and a two-sentence overview. Check that the overview covers the whole visual rather than one striking detail.
- Second pass: for each Task 2, underline every limiting word and write one sentence describing what a complete answer must do. Build the paragraph plan only after that sentence is precise.
- Third pass: complete the responses under time pressure, then review task completion before vocabulary. Ask first whether any stage, comparison, view, or question was left unanswered.
Questions about Cambridge IELTS 21 Writing
Does Cambridge IELTS 21 contain official model answers?
It contains selected candidate responses with official scores and examiner comments. They are best used to understand why a response received its score, not copied as perfect model answers.
Can these four tests predict 2026 IELTS Writing questions?
They show current task design and assessment priorities, but four tests cannot reliably predict which visual, essay type, or topic will appear next.
What should I practise first?
Start with Task 1 overviews and Task 2 scope checks. Both exercises train the same ability: identifying the central job before adding detail or advanced language.
