Your preparation might be flawless, but one incorrectly filled bubble on the MCQ answer sheet can cost you everything. The PPSC uses machine-scored OMR (Optical Mark Recognition) sheets, and machine scoring is considered final - there's no manual review or second chance.
This guide covers the official PPSC instructions for filling the answer sheet, with clear examples of correct and incorrect methods.
General Rules for the MCQ Answer Sheet
Before you start marking answers, keep these fundamental rules in mind:
- Use a black marker (preferred) or a blue marker if black is unavailable.
- Write the paper code and fill the paper code bubble exactly as printed on the question paper.
- Fill answer circles (bubbles) completely - do not leave any white space inside the bubble.
- Avoid multiple responses - only one bubble per question should be filled.
- No cutting, erasing, or correction pen is allowed on the answer sheet.
- Do not fold or damage the answer sheet in any way.
- Avoid stray marks, rough work, or extra filling - the machine may read these as wrong answers.
- You are responsible for any incomplete or wrongly filled information. PPSC will not rectify errors on your behalf.
Important: It is mandatory to write the paper code AND fill the relevant bubble code on your answer sheet. Failure to do so will result in your answer sheet not being marked and your candidature being cancelled.
How to Correctly Fill the Paper Code
The paper code (A, B, C, or D) is printed on your question paper. You must do two things:
- Write the paper code letter in the designated box
- Fill the corresponding bubble completely
Correct Example
| Action | Status |
|---|---|
| Paper Code (A) written in the box | ✅ Done correctly |
| Bubble for Code (A) filled accurately | ✅ Done correctly |
Both steps must be completed. Writing the letter alone is not enough - the machine reads the bubble, not your handwriting.
How to Correctly Fill Answer Bubbles
When marking your answers:
- Fill the bubble completely from edge to edge
- Use a single, clean stroke - the entire circle should be darkened
- Do not go outside the bubble boundary
- Mark only one bubble per question
Common Mistakes That Get Your Answer Sheet Rejected
Wrong Paper Code Filling
| Mistake | What Went Wrong |
|---|---|
| Paper Code (B) written but wrong bubble filled | You wrote "B" but filled bubble "A" or another code - mismatch |
| Paper Code (A) written but bubble not filled | You wrote the letter but forgot to fill the bubble - machine can't read it |
| Paper Code (A) not written but bubble filled | You filled the bubble correctly but didn't write the letter - incomplete |
| Paper Code neither written nor bubble filled | Both fields are empty - your sheet will not be processed |
| Paper Code not written but multiple bubbles filled | You filled more than one bubble code - this invalidates the paper code |
Wrong Answer Bubble Filling
| Mistake | What Happens |
|---|---|
| Additional filling | You filled the correct bubble but also partially marked another - machine may read this as two answers (wrong) |
| Improper filling | The bubble is not filled completely - partially filled bubbles may not be detected by the machine |
| Stray marks near a filled bubble | You accidentally made marks near your answer - the machine may interpret stray marks as additional answers |
| Stray mark on a blank item | Even a small accidental mark on a question you skipped can be read as an answer by the machine |
Tips for a Clean Answer Sheet
- Practice bubble filling before exam day - buy an OMR practice sheet and get comfortable with the marker
- Bring the right marker - a good quality black permanent marker with a fine tip works best
- Check your paper code first - before answering any question, write and bubble the paper code
- Don't rest your marker hand on the answer sheet - this can create stray marks
- Keep rough work on the question paper - never write anything extra on the answer sheet
- Double-check before submitting - ensure only one bubble is filled per question
- Handle with care - don't fold, crumple, or bend the answer sheet
What If You Make a Mistake?
Unfortunately, there is no way to correct a mistake on the PPSC MCQ answer sheet:
- Cutting is not allowed
- Erasing is not allowed
- Correction pen/fluid is not allowed
This is why it's critical to be careful and deliberate with every bubble you fill. If you're unsure about an answer, skip it and come back later - but never mark two bubbles for the same question.
Remember: Negative Marking Applies
In PPSC MCQ papers, 0.25 marks are deducted for each incorrect answer. Combined with the strict answer sheet rules, this means:
- A stray mark on a blank question = an "incorrect answer" = minus 0.25 marks
- Multiple bubbles filled = incorrect answer = minus 0.25 marks
- Improperly filled bubble = may not be detected = zero marks for that question
Your answer sheet discipline directly impacts your score.
Key Takeaway
The MCQ answer sheet is machine-scored and the result is final. No appeals or corrections are entertained after submission. Take your time filling each bubble carefully, avoid stray marks, always mark the correct paper code, and bring a proper black marker. A few seconds of care on each bubble can save you from losing marks you rightfully earned.
