Grammar Mistakes That Cost You Band Points in IELTS Speaking

Grammar mistakes in IELTS speaking affect two criteria:

1. Grammatical Range & Accuracy (directly)
2. Fluency & Coherence (indirectly—errors interrupt flow)

Many candidates think they need to use complex grammar to score Band 7. Wrong.

Band 7 means: mostly correct simple and complex structures, with rare errors.

The difference between Band 6 and Band 7 is error frequency, not complexity.

1. Tense Shifts

Switching between tenses without reason. Especially common when describing experiences.

Example (Band 6): "I go to the gym last week. I was lifting weights and I exercise regularly..."

Correct (Band 7): "I went to the gym last week. I was lifting weights and I exercise regularly now..."

How examiners view this: You don't fully control tense usage.

2. Missing Articles (a, an, the)

English requires articles before nouns. This is very noticeable to examiners.

Example (Band 6): "I like reading books. Books are interesting because they provide knowledge."

Correct (Band 7): "I like reading books. The books are interesting because they provide knowledge."

Actually, the first example might be acceptable in some contexts (talking about books in general). The key is consistency.

Real error: "I went to restaurant last night" (missing "a") "I study at university in city" (missing "the")

3. Subject-Verb Agreement

Singular subjects need singular verbs. Plural subjects need plural verbs.

Example (Band 6): "My friends is very supportive." "The team are working hard" (British English: acceptable)

Correct (Band 7): "My friends are very supportive."

4. Incorrect Verb Forms

Using base form when you need past or gerund, or vice versa.

Example (Band 6): "I enjoy to read books." "I am finishing my degree next year."

Correct (Band 7): "I enjoy reading books." "I finish my degree next year."

5. Preposition Errors

Using wrong prepositions is very noticeable and difficult to understand.

Example (Band 6): "I'm interested in music"—wait, should be "interested in" or "passionate about"? "I'm good for English"

Correct (Band 7): "I'm interested in music" "I'm good at English"

Why it matters: Prepositions are fundamental. Errors signal incomplete language control.

6. Word Order

English has strict word order rules. Violating them sounds unnatural.

Example (Band 6): "I very much like this movie." "I recently have finished a project."

Correct (Band 7): "I really like this movie." "I have recently finished a project."

7. Conditional Errors

Mixing conditional forms (If + present, will + verb vs. If + past, would + verb)

Example (Band 6): "If I would go to Japan, I will visit temples."

Correct (Band 7): "If I go to Japan, I will visit temples." "If I went to Japan, I would visit temples."

Examiners listen for control and consistency, not perfection.

Band 6 grammar profile:

• Errors appear every 2-3 sentences
• Mix of major (subject-verb) and minor (article) errors
• Inconsistent performance (correct one moment, wrong the next)

Band 7 grammar profile:

• Errors rare—maybe one per minute of speech
• Simple structures used correctly
• Complex structures attempted but mostly correct
• Consistent performance

The key: Pattern of mistakes, not isolated errors.

If you make the same error repeatedly (e.g., always "I am enjoy" instead of "I enjoy"), examiners assume you don't fully control that structure.

If you make occasional errors in complex sentences you're attempting, examiners assume you're trying to stretch your range (which is Band 7 behavior).

Don't try to fix all grammar at once. Identify your specific patterns:

1. Record a full Cue Card (2 minutes)

2. Transcribe it (write down everything you said)

3. Count errors by type:

   • How many tense shifts?
   • How many article errors?
   • How many verb form errors?
   • How many other errors?

4. Identify your top 2-3 patterns

   Example: "I make 5 tense shifts and 3 article errors per Cue Card."

5. Create a simple checklist Before speaking: "Check tense consistency. Check articles before nouns."

6. Practice focused improvement Next Cue Card: Focus only on tense and articles. Ignore everything else.

7. Re-record and verify How many errors now?

Week 1: Identify Your Top 2 Patterns

Record a Cue Card. Count errors by type. Identify the two types you make most.

Week 2: Practice Minimal Sentences

Use only simple sentences with your problem grammar.

Example (if tense is your issue): "I went to the gym. I exercised. I felt tired. I went home."

Get 100% accuracy here before moving to complex sentences.

Week 3: Introduce One Complex Structure

Add complexity while focusing on your problem area.

Example: "Because I went to the gym, I felt energized."

Week 4: Full Cue Card with Checklist

Speak a full Cue Card. Before speaking, review your checklist: "Watch tense. Watch articles."

Month 2: Add Your Third-Most-Common Error

Repeat the 4-week process for your next error pattern.

The Timeline

Expect to fix one grammar pattern in 4-6 weeks of focused practice. Most Band 6 candidates can reach Band 7 in Grammatical Range within 2-3 months by targeting their specific errors.

Start of month 1: Maria records a Cue Card. Count:

• 6 tense shifts
• 4 article errors
• 2 verb form errors

Grammatical Range score: Band 6

Focus: Tense consistency

Maria practices weeks 1-4 focusing on tense.

Week 4 re-recording: 1 tense shift (down from 6)

Focus: Article errors

Maria practices weeks 5-8 focusing on articles.

Week 8 re-recording:

• 1 tense shift
• 2 article errors (down from 4)

Score after 2 months: Band 7 in Grammatical Range

She still makes 3 errors in a 2-minute Cue Card, but the patterns are fixed. Performance is consistent.

Grammar improvement is not about reaching perfection. It's about fixing patterns and building consistency.

The candidates who improve fastest aren't those who study grammar rules passively. They're the ones who:

1. Identify their specific error patterns
2. Practice targeted fixes
3. Track improvement over time
4. Add new patterns once old ones are fixed

Record yourself. Transcribe. Count. Fix. Repeat.

This systematic approach moves you from Band 6 to Band 7 faster than generic "improve your grammar" advice ever will.
