ieltsvietnam - Essential Steps to Achieve a High Score

Grammatical range and accuracy is worth a quarter of both your Writing and Speaking scores, and for Vietnamese learners it is often the criterion that quietly holds a score at Band 6 instead of 7. Vietnamese and English structure sentences very differently, which produces a predictable set of errors that repeat across thousands of candidates. The good news is that predictable errors are fixable errors. This guide identifies the grammar mistakes Vietnamese learners most commonly make and sets out the essential steps to build both accuracy and range.

What examiners mean by range and accuracy

The criterion has two halves, and you need both. Range means using a variety of structures — not only simple sentences but also complex ones with subordinate clauses, conditionals, relative clauses, and passive forms where appropriate. Accuracy means producing those structures with few errors.

The key insight is the balance between them. Moving from Band 6 to Band 7 typically requires "frequent error-free sentences" alongside a range of structures. A candidate who writes only simple sentences accurately is capped by limited range; one who attempts complex structures but makes constant errors is capped by accuracy. The target is ambitious structures that you can control. Do not chase complexity you cannot get right.

This balance explains a pattern many learners find puzzling: someone who writes cautiously in short, safe sentences and someone who writes long, tangled sentences full of slips can end up at the same band, held back from opposite directions. The path upward is not to abandon complex sentences but to add them gradually, one structure at a time, keeping accuracy high as range grows. Reaching too far too fast usually costs more marks in errors than it earns in variety.

The errors Vietnamese learners make most

Because Vietnamese grammar works differently from English, certain mistakes recur predictably. Recognising your own patterns is the first step to fixing them:

• Articles (a, an, the): Vietnamese has no articles, so learners omit them ("government should invest in education") or overuse them. This is one of the most frequent and visible errors.
• Verb tenses and endings: Vietnamese verbs do not change form, so the past tense "-ed" and third-person "-s" are often dropped ("she work," "he live in Hanoi," "yesterday I go").
• Plurals: the plural "-s" is frequently missing ("many student," "two problem").
• Subject-verb agreement: "the number of people are rising" instead of "is rising."
• Prepositions: "depend of" instead of "depend on," "different with" instead of "different from."

None of these individually is serious, but repeated across an essay they steadily lower your accuracy band.

Build range with a few reliable structures

You do not need dozens of grammar structures to show range — a handful, used accurately and appropriately, is enough. Master these building blocks and vary them naturally:

• Complex sentences with subordinating conjunctions: "Although online learning is convenient, it lacks personal interaction."
• Relative clauses: "Students who study abroad often gain independence."
• Conditionals: "If governments invested more in public transport, congestion would fall."
• The passive voice where it fits, especially in Academic Writing Task 1: "The data was collected over five years."

The aim is a natural mix of simple and complex sentences. An essay of only complex sentences can become hard to read; alternating sentence length is itself a mark of control.

Accuracy comes from noticing, not just knowing

Most learners already "know" that verbs take "-s" in the third person, yet still drop it under pressure. The problem is not knowledge but noticing — catching the error while producing language in real time. Closing this gap is the heart of improving accuracy.

The most effective tool is an error log. After every piece of Writing or recorded Speaking, list the specific mistakes you made and their corrections. Review this log weekly. Over time you will notice yourself catching a dropped article or missing plural as you write, because your attention has been trained toward it. Fixing five recurring errors this way often raises your accuracy faster than learning any new structure.

Practise grammar in production, not just exercises

Grammar drills and gap-fill exercises build knowledge, but IELTS tests grammar in production — spontaneous writing and speaking. You must practise producing correct structures under realistic conditions, not only recognising the right answer in a workbook.

Write timed essays and record spoken answers, then check them specifically for your known error patterns before looking at anything else. Rewrite the essay with corrections, consciously reusing the structures you got wrong. For Speaking, self-correction is actually rewarded — if you say "he go" and immediately fix it to "he goes," that shows control rather than weakness, so do not be afraid to correct yourself naturally. Getting feedback from a teacher or capable partner is essential here, because the errors most damaging to your score are usually the ones you can no longer see yourself.

A step-by-step plan to raise your grammar band

Turn all of this into a routine. First, diagnose: write one timed essay and record one spoken answer, then identify your three most frequent error types. Second, target them one at a time — spend a week focused on articles, the next on verb endings, and so on, rather than trying to fix everything at once. Third, log every error and review the log weekly until the fixes become automatic.

Fourth, expand range gradually by adding one new structure at a time and using it until it is reliable before adding another. Fifth, seek regular feedback so you catch errors you cannot see. And keep your expectations realistic — no plan guarantees a specific band, but this deliberate, pattern-focused approach is one of the most dependable ways to lift grammar from a ceiling into a strength.

Grammatical range and accuracy rewards control above all: a manageable set of structures used correctly, with the predictable Vietnamese-speaker errors — articles, verb endings, plurals, prepositions — steadily trained out through logging and feedback. Target your specific patterns, practise in real production, and let range grow as accuracy holds. For grammar-focused Writing feedback, targeted exercises, and Speaking practice built around the challenges Vietnamese learners face, IELTS Vietnam offers the structured support that turns recurring mistakes into consistent, confident marks.
