📘 Introduction: Why Grammar Mistakes Cost You Marks
Common grammar mistakes in competitive exams are one of the biggest reasons why students lose marks despite knowing the rules. In exams like SSC, Banking, UPSC, and NET, even a small mistake in grammar can reduce your accuracy and affect your final score.
Many students study grammar but still make repeated errors because they do not understand the concepts deeply or fail to apply them correctly in exam situations. This article explains the most common grammar mistakes in competitive exams with clear rules, detailed explanations, and simple examples to help you avoid them easily.
—
👉 In competitive exams, you don’t lose marks because of lack of knowledge
👉 You lose marks because of small grammar mistakes
And the reality is:
✔ These mistakes are common
✔ These mistakes are repeated
✔ These mistakes are avoidable

❌ He go to school
❌ She is good in English
👉 Why does this happen?
Because they:
- Don’t understand deeply
- Don’t practice properly
- Don’t analyse mistakes
This article will help you:
✔ Understand mistakes clearly
✔ Know why they happen
✔ Learn how to avoid them permanently
🔴 1. Subject-Verb Agreement Errors
📌 What is the mistake?
Subject and verb must agree in number (singular/plural).
❌ Common Wrong Thinking:
Students look at the nearest noun, not the real subject.
📌 Example:
❌ The list of items are on the table
✅ The list of items is on the table
👉 Why?
- Subject = list (singular)
- “of items” = extra information
📌 Another Example:
❌ A number of students is absent
✅ A number of students are absent
👉 Why?
- “A number of” = plural meaning
- So verb = plural
🎯 Exam Tip:
👉 Always identify the real subject, not nearby words.
🔴 2. Incorrect Use of Tenses
📌 What is the mistake?
Students mix time reference and verb form.
📌 Example:
❌ I have completed my work yesterday
✅ I completed my work yesterday
👉 Why?
- “Yesterday” = past time
- Present perfect cannot be used
📌 Another Example:
❌ She is knowing the answer
✅ She knows the answer
👉 Why?
Some verbs (know, believe, understand) are stative verbs
→ They do NOT take continuous form
🎯 Exam Tip:
👉 Always check:
- Time word (yesterday, since, now)
- Then choose tense
🔴 3. Wrong Use of Articles (A, An, The)
📌 What is the mistake?
Students focus on letters, not sound.
📌 Example:
❌ A honest man
✅ An honest man
👉 Why?
- “Honest” → silent ‘h’ → vowel sound
📌 Example:
❌ He is in the hospital (Indian usage confusion)
✅ He is in hospital (British exam pattern)
📌 Example:
❌ She is best student
✅ She is the best student
👉 Superlative always takes “the”
🎯 Exam Tip:
👉 Focus on sound, not spelling
🔴 4. Preposition Errors
📌 What is the mistake?
Students translate directly from Hindi/Marathi.
📌 Example:
❌ She is good in English
✅ She is good at English
📌 Example:
❌ He is married with her
✅ He is married to her
📌 Example:
❌ Discuss about the issue
✅ Discuss the issue
👉 “Discuss” does NOT need “about”
🎯 Exam Tip:
👉 Learn fixed combinations (collocations)
🔴 5. Double Negatives
📌 What is the mistake?
Using two negatives in one sentence.
📌 Example:
❌ I don’t know nothing
✅ I don’t know anything
📌 Why Wrong?
Two negatives = positive meaning (confusing)
🎯 Exam Tip:
👉 Only one negative word allowed
🔴 6. Pronoun Errors
📌 What is the mistake?
Wrong pronoun form or unclear reference.
📌 Example:
❌ Me and Rahul went there
✅ Rahul and I went there
👉 “I” is subject, not “me”
📌 Example:
❌ Each student must bring their book
✅ Each student must bring his book
👉 “Each” = singular
🎯 Exam Tip:
👉 Match pronoun with:
- Number
- Gender
- Person
🔴 7. Confusion Between Similar Words
📌 What is the mistake?
Words look similar but meanings differ.
📌 Examples:
❌ He is taller then me
✅ He is taller than me
❌ Your going there
✅ You’re going there
📌 Why Happens?
👉 Lack of attention and practice
🎯 Exam Tip:
👉 Learn commonly confused words list
🔴 8. Sentence Structure Errors
📌 What is the mistake?
Wrong word order or missing inversion.
📌 Example:
❌ Hardly he had reached
✅ Hardly had he reached
👉 Rule:
“Hardly / No sooner” → inversion required
🎯 Exam Tip:
👉 Watch for:
- Hardly
- No sooner
- Rarely
🔴 9. Active-Passive Voice Errors
📌 What is the mistake?
Incorrect verb form in passive.
📌 Example:
❌ A letter written by him
✅ A letter was written by him
📌 Why?
Passive =
👉 Object + helping verb + V3
🎯 Exam Tip:
👉 Always check:
- Tense
- Helping verb
🔴 10. Direct & Indirect Speech Errors
📌 What is the mistake?
Wrong tense and pronoun changes.
📌 Example:
❌ He said, “I am tired” → He said he is tired
✅ He said he was tired
📌 Why?
👉 Reporting verb in past → tense changes
🎯 Exam Tip:
👉 Check:
- Tense
- Pronoun
- Time words
🔴 11. Modal Errors
📌 What is the mistake?
Wrong use of can, could, may, might.
📌 Example:
❌ He can be at home (past)
✅ He could be at home
🎯 Exam Tip:
👉 Use:
- Can → present ability
- Could → past / possibility
🔴 12. Ignoring Context
📌 What is the mistake?
Students apply rule blindly without meaning.
📌 Example:
❌ She has been living here since 5 years
✅ She has been living here for 5 years
📌 Why?
- Since → point of time
- For → duration
🎯 Exam Tip:
👉 Always check meaning of sentence
