You studied hard.
Your preparation is solid.
Yet in the exam, 15–25 marks vanish because of small, ignored habits.
This is the painful truth:
Exams are lost more because of execution mistakes than lack of study.
Toppers don’t study extra chapters.
They simply avoid these exam killers.
Let’s fix that — once and for all.

Avoid These Exam Day Mistakes
1. This Habit Destroys Exam Performance: Checking Phone for Time 📱💀
One glance at your phone feels harmless.
In reality, it destroys your rhythm.
What goes wrong:
Phone out → 2 minutes wasted
Mind distracted
Focus broken
Anxiety triggered
Repeat this 4–5 times = 10 minutes lost.
That’s 2 easy questions = 10 marks gone.
What toppers do instead:
Simple wristwatch (₹100 is enough)
Time checked instantly
Zero distraction
✅ Fix:
Set your wristwatch the night before. Never touch your phone in the exam hall.
2. Avoid Failure in the Exam Hall: Never Leave Questions Blank 🚫
Leaving a question blank is the biggest silent score killer.
Reality check:
Blank answer = 0 marks
Attempted answer = partial marks almost guaranteed
Examples:
Science: Diagram wrong, labels correct → 2–3 marks
Maths: Final answer wrong, steps correct → 3–4 marks
Theory: Half content written → 50–60% marks
❌ Blank page = ego
✅ Attempt = intelligence
✅ Rule:
Attempt every question, even if you are unsure.
3. Exam Do’s and Don’ts List (Save This) ✅🚫
✔ DO THIS:
Read each question 3 times
Underline keywords
Number your steps (1, 2, 3…)
Draw large, labeled diagrams
Circle final answers
Use last 5 minutes only for review
❌ NEVER DO THIS:
Check time on phone
Leave questions blank
Draw tiny diagrams
Skip units (kg, m/s², J)
Write the same answer twice
These small actions decide rank difference.
4. Score Better by Avoiding This Mistake: Illegible Handwriting ✍️😵
Examiners don’t decode handwriting.
They skip it.
Bad handwriting = marks silently cut.
Smart writing rules:
Write slightly bigger
Leave margins
Use black pen for main answers
Avoid overwriting and cutting
Maintain spacing
🟢 Neat presentation = 5–7 free marks
5. Avoid These Exam Day Mistakes: Wrong Question Numbering 🔄❌
One wrong question number can destroy two answers at once.
Common disaster:
Answer of Q5 written under Q3
Examiner confused
Both answers risk zero
Safe format:
✅ Always BOX the question number before starting.
🔥 Hidden Exam Killers Most Students Ignore
No organized rough work
Tiny diagrams with no impact
Writing formulas without units
Wasting remaining time instead of reviewing
Not underlining keywords
Each one costs 2–3 marks silently.
