March 9, 2026Most Common IELTS Writing Mistakes in 2026: The Band 9 Rescue Guide
As we move through 2026, the criteria for Grammatical Range and Accuracy (GRA) have become the deciding factor for many candidates. At UpScore IELTS, we have analyzed thousands of essays to identify the specific "systemic errors" that are holding candidates back.
Whether you are preparing in Kathmandu or anywhere else in the world, these are the five traps you must avoid.
1. The "Phonetic" Article Trap
Many candidates incorrectly use a/an based on spelling rather than sound.
-
The Mistake: Writing "an university" or "a honest mistake."
-
The Band 9 Fix: Always listen to the first sound. Use "a" for the consonant sound in a university and "an" for the silent 'h' in an honest mistake.

2. Losing "Clause Control" (Run-on Sentences)
Attempting to write "complex" sentences often leads to long, confusing run-ons.
-
The Mistake: Stringing multiple ideas together with "and" or "but" without proper punctuation.
-
The Band 9 Fix: Limit your complex sentences to two main ideas connected by a subordinator like although or because. Break three-line sentences into two shorter, clearer ones.

3. Subject-Verb Agreement "Slips"
When the subject is separated from the verb by a long phrase, many candidates lose track of the grammar.
-
The Mistake: "The quality of the locally grown fruits are important."
-
The Band 9 Fix: Identify the true subject (The quality) and ensure the verb matches it (is).

4. Uncountable Noun Pluralization
Using plural forms for nouns that should be uncountable is a hallmark of a Band 6 essay.
-
The Mistake: Providing "advices," "informations," or "equipments."
-
The Band 9 Fix: These words never take an 's'. Use the zero article or phrases like "a piece of advice" instead.

5. Weak Prepositional Collocations
Small words like in, on, and at often cause naturalness issues.
-
The Mistake: Writing "impact for" or "reason of."
-
The Band 9 Fix: Master high-level collocations like "impact on" and "reason for" to improve your Lexical Resource score.
