PGECET – Foundation & Exam Strategy
Topic: Marking Scheme
📌 Simple Explanation
In PGECET, each of the three papers (Computer Science/IT, Mathematics, General Aptitude) contains 40 multiple‑choice questions.
- Correct answer: +4 marks
- Wrong answer: ‑1 mark
- Blank: 0 marks
The total marks for the exam are 160 (40 × 4 × 3). The exam uses a negative‑marking system to discourage random guessing.
📑 Key Points
| Item | Details |
|---|---|
| Paper structure | 3 papers, 40 MCQs each |
| Marking per question | +4 for correct, –1 for wrong, 0 for blank |
| Total marks | 160 |
| Cut‑off | Usually 50 % of total marks (≈ 80 marks) – check the latest cutoff list |
| Negative marking rationale | Prevents random guessing; ensures higher chance of correct answer is rewarded |
| Time allocation | 90 minutes per paper (≈ 2 min 15 s per question) |
| Scoring strategy |
- Answer all sure questions first.
- For uncertain ones, guess only if the probability of being correct is ≥ 25 % (i.e., 1 out of 4). | | Conversions | Marks → Percentage: ((\text{Obtained marks}/160) \times 100) |
📚 Worked Example
Scenario
A candidate attempts all 120 questions (3 papers × 40 questions).
- Correct: 30 questions
- Wrong: 5 questions
- Blank: 5 questions
Calculations
| Category | Count | Marks per Q | Total Marks |
|---|---|---|---|
| Correct | 30 | +4 | 30 × 4 = 120 |
| Wrong | 5 | –1 | 5 × (‑1) = –5 |
| Blank | 5 | 0 | 0 |
| Total | 115 marks |
Percentage
[ \text{Percentage} = \frac{115}{160} \times 100 \approx 71.9% ]
Minimum correct answers needed for 50 % (80 marks)
If no questions are left blank:
( \text{Correct} \times 4 = 80 \Rightarrow \text{Correct} = 20 )
If you have (x) wrong answers, you’ll need
(4C - x \ge 80) → (C \ge \frac{80 + x}{4})
Example: 5 wrong → (C \ge \frac{85}{4} = 21.25) → at least 22 correct.
⏱ Quick Revision Summary
| What to Remember | How to Apply |
|---|---|
| +4 marks per correct | Aim for certainty before guessing |
| ‑1 mark per wrong | Avoid random guessing unless you’re confident |
| 0 for blanks | Skip only if unsure of all options |
| 160 total marks | Keep track of marks paper‑wise |
| Cut‑off ~80 marks | Target ≥ 80 marks; plan your strategy accordingly |
| Time: 90 min/paper | Roughly 2 min 15 s per question; pace yourself |
Final Tip
Use the marking scheme to plan your answer sheet:
- Answer all questions you’re certain
