CDS 2026 Marks Calculator

IMA, INA and Air Force Academy: +5/6 for a right answer, −5/18 for a wrong one; +1 for a right answer, −1/3 for a wrong one. Officers' Training Academy: +5/6 for a right answer, −5/18 for a wrong one.

300 marks: English (120 questions), General Knowledge (120 questions), Elementary Mathematics (100 questions).

No. Only wrong answers carry a penalty. A question left blank scores zero.

Compare your responses with the official answer key published by the exam body. Count only the questions you marked: those matching the key are right, the rest are wrong.

One third of the marks assigned to that question, in the notification’s own words. That is not the same as a third of a mark: English and General Knowledge carry 100 marks over 120 questions, so each question is worth 5/6 of a mark and a wrong answer costs 5/18, about 0.28. Elementary Mathematics is 100 marks over 100 questions, so there a wrong answer costs exactly 1/3.

For the Indian Military Academy, the Indian Naval Academy and the Air Force Academy, all three papers: English, General Knowledge and Elementary Mathematics, 300 marks in total. For the Officers’ Training Academy, only English and General Knowledge, 200 marks in total.

Yes. The notification says that if you give more than one answer it is treated as a wrong answer, and the same penalty applies, even if one of the answers you marked happens to be correct.

No. This calculator scores the written examination only. The notification sets the maximum marks for the interview equal to the written examination — 300 for the IMA, INA and Air Force Academy and 200 for the OTA — and those are awarded separately at the Services Selection Board.
