How to Fix Logic and Grammar Errors in IELTS Task 2 (Real Case Study)

Getting a Band 6.5 in IELTS Writing Task 2 is a great achievement. It means your English is good. But “good” isn’t enough for everyone. Many candidates need a Band 7, 7.5 or 8.0 for university admission or immigration points. And this is the hardest jump to make.

Why? Because the difference between a Band 6.5 and a Band 8 isn’t usually about learning more “big words.” It is about precision. It is about avoiding subtle logic errors (Coherence) and complex grammar slips (Accuracy) that even advanced students make.

In this post, we are going to analyze a real student essay that scored a Band 6.5. Using the WriteWiseAI IELTS writing task 2 checker, we will identify the specific “invisible” mistakes holding it back, and use our Iterative Feedback Loop to revise it into a Band 8.0 masterpiece.

The Case Study: The "Junk Food" Debate

The Task:
Some people state that schools should have a social responsibility to encourage children not to eat junk food. Others believe that parents should take responsibility for their children’s eating habits. Discuss both views and state your opinion.

The Student’s First Draft (Band 6.5):
Read the following essay carefully. It looks strong, doesn’t it?

“It is alleged that, in today’s modern world, children are following healthy habits such as eating nutritious meals. This is a controversial topic worldwide. I agree with this statement: parents play a crucial role, while others believe that social responsibilities such as schools are also important in society and in children’s lives. parents are important in children life and their attitudes for their future.

Schools play a crucial role in children’s lives when they study. They have to follow rules at school and learn about life. For instance, when I was studying, they taught us about food and nutrition, and also how it affects our brain and physiology. Moreover, unhealthy food can damage our lifestyle and increase the risk of depression. I remember my friend Ali; he was an overweight boy and did not have confidence at school. Meanwhile, this mindset could affect his future in society.

In contrast, I believe that parents are very important in children’s lives because they shape their attitudes and lifestyles. The home environment is also crucial; for instance, when parents pay attention to an athletic lifestyle, children cannot easily follow bad behaviors. This approach can affect children’s lifestyles and their future. For example, Cristiano Ronaldo is a professional football player, and his son Junior, like him, follows a healthy diet and engages in physical activity.

In contrast, I believe in this statement: parents have a greater influence on children’s lifestyles and their healthy meals. However, every place where children spend time can also affect their behaviors.”

The AI Analysis: A 360° Breakdown of a Band 6.5

When this essay was submitted to our free ielts essay checker, it received an Overall Band 6.5.

  • Task Achievement: 7
  • Coherence & Cohesion: 6
  • Lexical Resource: 7
  • Grammatical Range & Accuracy: 6

This is a solid essay. The vocabulary is decent (“physiology,” “athletic lifestyle”). But to reach Band 8, we need to fix specific issues flagged by the AI report.

  1. Task Achievement (The “Confusing Intro”)

  • The Mistake: The prompt implies that junk food is a problem. However, the student’s opening sentence says: “It is alleged that… children are following healthy habits.”
  • The AI Insight: The checker flagged this as “Contradictory/Confusing.” The student contradicts the premise of the question immediately. A Band 8 essay must have a crystal clear introduction that acknowledges the problem.

 

  1. Coherence & Cohesion (The “Fake Linking Words”)

  • The Mistake: This is the reason Coherence dropped to a Band 6. The student used high-level linking words incorrectly.
    • “Meanwhile”: The student wrote: “he did not have confidence… Meanwhile, this mindset could affect his future.”
      • Correction: “Meanwhile” indicates two things happening at the same time. The student meant “Consequently” or “As a result” (Cause and Effect).
    • “In contrast”: The student used this to start their opinion paragraph, but their opinion wasn’t a direct contrast to the previous point.
  • The AI Insight: Just using “fancy” transition words doesn’t boost your score. If you use them illogically, they lower your score. The IELTS essay correction feature identified these as “Cohesive Errors.”

 

  1. Grammatical Range & Accuracy (The “Run-On” Conclusion)

  • The Mistake: The conclusion is just one long sentence: “In contrast, I believe in this statement… however, every place where children spend time…”
  • The AI Insight: This is a “Run-On Sentence.” Two independent ideas are mashed together. To score high in GRA, your complex sentences must be grammatically perfect.

 

  1. Lexical Resource (Repetitive Vocabulary)

  • The Mistake: The student used the word “important” and “crucial” five times. They also repeated “lifestyles” frequently.
  • The AI Insight: While the words are correct, the lack of variety limits the score. The checker suggested synonyms like “paramount,” “instrumental,” or “significant influence.”

The Revision: From Good to Great

Using the Iterative Feedback Loop, the student revised the essay. They didn’t rewrite the whole thing; they just targeted the red flags in the report.

Here is the Revised Version (Band 8.0):

“The debate regarding accountability for children’s dietary choices is increasingly significant in the modern world. While some proponents argue that educational institutions have a social duty to curb the consumption of junk food, I firmly believe that parents bear the primary responsibility for shaping their children’s eating habits.

Schools certainly play an instrumental role in a child’s development, primarily through education and environmental control. They provide a structured setting where students can learn about nutrition and physiology. For instance, during my education, we were taught how processed food can damage our health. However, knowledge alone is often insufficient. Take my friend Ali; despite our health classes, the school canteen sold high-calorie snacks. As a result, he became overweight and lacked confidence. Consequently, this physical state negatively affected his future social interactions, suggesting that schools often send mixed messages.

On the other hand, I believe that parents are paramount in shaping children’s attitudes because they act as the ‘gatekeepers’ of the home. Since children generally cannot buy their own groceries, parents decide what is available to eat. Furthermore, parental modeling is powerful. When parents model an athletic lifestyle, children are less likely to adopt poor dietary habits. For example, Cristiano Ronaldo is a professional athlete known for his discipline, and his son, imitating him, follows a strict, healthy diet. This demonstrates that domestic influence is far stronger than institutional rules.

In conclusion, while schools can educate and enforce restrictions during the day, I maintain that parents have the greatest influence on children’s lifestyles. It is the daily habits established at home that ultimately determine a child’s long-term health, though a collaborative effort is likely the ideal solution.”

Why The Revised Version Wins

Let’s look at the specific score improvements based on the IELTS writing task 2 checker analysis:

  1. Task Achievement (Depth & Clarity):
    • The Position: The introduction now clearly paraphrases the prompt (“accountability,” “curb consumption”) and states a firm position immediately.
    • The Development: Unlike the first draft, the ideas are now fully extended. The “Ali” example explains why he gained weight (the school canteen), and the “Parents” paragraph explains how they control diet (acting as “gatekeepers”). This depth is essential for a Band 8.
  2. Coherence & Cohesion (Logic):
    • Before: “Meanwhile” (Incorrectly used to show result).
    • After:Consequently” (Correctly shows cause-and-effect).
    • Before: “In contrast” (Incorrectly used to start the conclusion).
    • After:In conclusion” (Correct signposting).
    • Result: The logic flows smoothly without confusing the reader.
  3. Grammar & Vocabulary (Precision):
    • Grammar: The run-on sentence in the conclusion was split into two clear, accurate sentences.

Vocabulary: Repetitive words like “important” were replaced with precise academic terms like “instrumental,” “paramount,” and “accountability.”

The "Hidden" Mistakes Only AI Can Find

It is easy to spot a spelling mistake. It is very hard to spot a logical fallacy or a misused cohesive device in your own writing.

This student thought “Meanwhile” was a sophisticated word. Without the Error Analysis from WriteWiseAI, they would have continued using it incorrectly in every essay, permanently capping their score at Band 6 for Coherence.

Don’t let “invisible” errors lower your score.
