Last updated: April 10, 2026 Quick answer The official 2026 prelims syllabus shows a 200-mark paper with 150 equal-mark questions. That makes each correct answer worth 1.33 marks, while each wrong answer deducts 0.33 marks. Use Actual Score mode if you know your correct and wrong answers. Use Safe Attempt Simulator if you are planning exam-day behavior. Scoring logic used here This tool is intentionally simple. It keeps the scoring model visible so aspirants can reason about accuracy and attempts instead of trusting a hidden number.

It uses the official 2026 prelims syllabus basis we could verify: 150 objective questions carrying equal marks across a 200-mark paper, with 1/3 mark deducted for each wrong answer.What is the difference between Actual Score and Safe Attempt Simulator? Actual Score is for when you already know your correct and wrong answers. Safe Attempt Simulator is for exam strategy: you enter attempts and expected accuracy to see what that behavior is likely to produce.Why does the simulator return a recommended attempt range instead of one perfect number? Because safe attempts depend on accuracy, not bravado. A range is more honest than pretending one magic number applies to everyone.
