Good Attempts Analysis

Because the Shift 2 paper was moderate to tough, the good attempts range differs from typical easier papers.

Expected Good Attempts Range:

Based on PW Faculty Analysis and Student Feedback:

• Excellent Performance: 50-55+ marks attempted with 80-85% accuracy
• Good Performance: 40-50 marks attempted with 75-80% accuracy
• Moderate Performance: 30-40 marks attempted with 70-75% accuracy

Critical Factors Affecting Good Attempts:

1. NAT/MSQ Correctness: Higher importance of accuracy over quantity
   • NAT questions require precise calculations (no negative marking but no partial credit either)
   • MSQ questions need all correct options for full marks
2. MCQ Strategy: Performance strongly influenced by careful MCQ selection
   • Negative marking makes random guessing counterproductive
   • Better to leave doubtful questions unattempted
3. Time Management: Moderate overall attempt level expected
   • Tougher questions required more time
   • Strategic skipping of very difficult questions was wise
4. Section Balance: Candidates who maintained balance across sections performed better
   • Focusing only on strong areas could limit overall score
   • General Aptitude's 15 marks should not be neglected

Important Note:

Exact good attempt figures will become clearer after:

• Official response sheet publication
• Official answer key release
• Normalization process across shifts
• Final cutoff declaration

Candidates should not be disheartened by lower attempt numbers if accuracy was maintained, as quality matters more than quantity in GATE.

Marking Scheme for GATE CSE 2026

Understanding the marking pattern is essential for accurate score prediction:

MCQ (Multiple Choice Questions):

1-Mark MCQs:

• Correct answer: +1 mark
• Incorrect answer: -1/3 mark (0.33 marks deducted)
• Unattempted: 0 marks

2-Mark MCQs:

• Correct answer: +2 marks
• Incorrect answer: -2/3 mark (0.67 marks deducted)
• Unattempted: 0 marks

MSQ (Multiple Select Questions):

• No negative marking for wrong answers
• Partial marking allowed for partially correct answers
• All correct options must be selected for full marks
• If all selected options are correct but incomplete, partial marks awarded
• If any selected option is wrong, zero marks awarded

NAT (Numerical Answer Type):

• No negative marking for wrong answers
• Answers must be precise (usually up to 2 decimal places)
• No partial marking in most NAT questions
• Range-based evaluation in certain cases
• Rounding conventions must be followed as per instructions

Strategic Implications:

This marking structure makes:

1. Careful MCQ attempts essential due to negative marking
2. Accurate NAT solving crucial for maximizing score
3. Strategic MSQ attempts beneficial as there's no negative marking
4. Selective answering more important than attempting all questions
