RRB NTPC (Non-Technical Popular Categories) recruits for station masters, clerks, goods guards, and similar railway posts through computer-based tests held by the Railway Recruitment Boards. The selection runs through CBT 1 and CBT 2, both objective and both carrying negative marking. CBT 1 has 100 questions worth 1 mark each (100 marks total) across General Awareness, Mathematics, and General Intelligence and Reasoning; CBT 2 has 120 questions worth 1 mark each.
Because scores are normalised across shifts and the merit list is drawn from CBT 2 (and the subsequent stages), every wrong answer that drags down your normalised score can cost you a posting. The calculator above lets you set the question count for either CBT to model your exact paper.
RRB NTPC applies one-third negative marking: every wrong answer deducts one-third of the marks for that question. Since each question is worth 1 mark, a wrong answer costs you 0.33 marks. Unattempted questions carry no penalty. The one-third rule is the same proportion used by UPSC, but because RRB questions are worth 1 mark rather than 2, the per-question deduction is half as large in absolute terms (0.33 versus 0.66).
Suppose in CBT 1 you attempt 90 of the 100 questions, getting 70 correct and 20 wrong.
Marks for correct: 70 × 1 = 70. Penalty for wrong: 20 × 0.33 = 6.67. Final score: 70 − 6.67.
Your net score is 63.33 out of 100.
Because RRB normalises raw scores across shifts before drawing the merit list, your relative accuracy matters more than your raw total. A candidate who attempts all 100 questions at 70% accuracy (70 correct, 30 wrong) scores 70 − 10 = 60, while a more selective candidate who attempts 80 at 85% accuracy (68 correct, 12 wrong) scores 68 − 4 = 64. The second candidate attempted twenty fewer questions and still came out ahead.
With a relatively light one-third penalty on 1-mark questions, an educated guess where you can rule out two options is usually worth taking. But blind guessing across the whole paper still erodes your normalised score. Use mock tests to measure your accuracy in General Awareness separately from Reasoning, and let that guide where you attempt and where you leave blank.
RRB NTPC selection does not end at CBT 1: you must clear CBT 1 to reach CBT 2, and the final merit is built largely from your normalised CBT 2 score. That means consistency matters more than a single strong paper — a candidate who scores moderately but cleanly across both stages will usually out-rank one who posts a high gross score wrecked by negative marking. The General Awareness section, with its current-affairs and static-GK questions, is where most candidates leak marks to confident-but-wrong answers, so treat it as the section to be most disciplined in. Run your expected attempts through the calculator above before exam day so you know in advance roughly what net score your accuracy is likely to produce.
RRB NTPC applies one-third negative marking. Each wrong answer deducts one-third of that question’s marks, which works out to 0.33 marks per wrong answer for the 1-mark questions used in CBT 1 and CBT 2.
Yes. Both stages of RRB NTPC are objective and apply the same one-third negative marking for every wrong answer. CBT 1 has 100 questions and CBT 2 has 120 questions.
No. Only wrong answers are penalised. Questions you leave blank score zero with no deduction.
Subtract one-third of your wrong-answer count from your correct-answer count. For example, 75 correct and 15 wrong gives 75 − (15 × 0.33) = 75 − 5 = 70. The calculator above applies this automatically.
Yes. Because the exam is held in multiple shifts with different question papers, raw scores are normalised before the merit list is prepared, so your relative accuracy matters as much as your raw total.
