IELTS Writing Task 1 question
The diagram below shows the manufacturing process for making sugar from sugar cane.
Summarise the information by selecting and reporting the main features, and make comparisons where relevant.
How sugar is produced from sugar cane
Student answer (Band 6.5)
The figure below illustrates the flow diagram of sugar production from sugar cane.
Overall, the process includes 7 steps, starting from upstream to finalize the downstream processing to sugar. The growing takes 12 to 18months. Starting from growing the sugarcane which is first step, and to finally drying and cooling it involves 7steps.
The 2nd step is harvesting, which can be done manually by farmers or automatically by machine. The harvested crop is sent to crusher for extract the juice in the 3rd step. After the filtration of the juice by limestone filter, It is sent to evaporator where the water of juice is evaporated and became syrup.
In the 6th step, the syrup is sent to cetrifuge where the machine separates sugar crystals from it by centrifugal force. Then, the separated sugar crystals are dried and cooled in a chamber. The diagram clearly demonstrates the detailed process step by step serially.

Task Achievement / Task Response — Band 6.0
You have identified the main stages of the process, which is a positive start. However, the response lacks a clear overview of the process as a whole, which is essential for a high band score. You mention '7 steps' twice, but the description of these steps is somewhat repetitive and lacks detail regarding the transition between stages. For example, the transition from the evaporator to the centrifuge is mentioned, but the crucial role of the centrifuge in separating crystals is not fully explained in the context of the overall flow. To improve, ensure you highlight the key stages clearly and provide a more cohesive summary of the transformation from raw material to finished product.
Coherence and Cohesion — Band 6.5
The response is organised into paragraphs, but the logical progression is slightly disjointed. While you use some cohesive devices like 'The 2nd step' and 'After the filtration', the flow between sentences feels mechanical. The paragraphing is also somewhat unbalanced, with a very short introductory paragraph and a lack of clear separation between the stages of the process. To improve, try to group the stages more logically—perhaps by separating the preparation, the extraction, and the final refining stages—and use a wider variety of linking words to connect your ideas more fluidly.
Lexical Resource — Band 6.5
Your vocabulary is generally adequate for the task, allowing you to describe the process clearly. You use some relevant technical terms such as 'centrifuge', 'evaporator', and 'limestone filter'. However, there are some minor inaccuracies in word choice, such as 'finalize the downstream processing to sugar' and 'became syrup', which sounds slightly unnatural. To achieve a higher band, focus on using more precise collocations and varied vocabulary to describe the changes in state, such as 'concentrated into syrup' or 'subjected to centrifugal force'.
Grammatical Range and Accuracy — Band 6.0
You demonstrate a mix of simple and complex sentence structures. However, there are several grammatical errors that affect the flow, such as 'starting from upstream to finalize the downstream processing to sugar' and 'sent to crusher for extract the juice'. Additionally, there are issues with article usage ('sent to crusher', 'sent to evaporator') and tense consistency. While these errors do not completely impede communication, they occur frequently enough to impact the overall accuracy. Focusing on subject-verb agreement and the correct use of articles will help improve your score in this area.
