UPSC Marks Calculator (Updated): GS and CSAT


The UPSC Prelims exam is an important stage in the Civil Services Examination, and every mark counts. To help you in this examination, we have developed a comprehensive UPSC Marks Calculator for both the General Studies (GS) and Civil Services Aptitude Test (CSAT) papers. With these calculators, you can calculate your marks, considering negative marking, which helps you improve your preparation strategy.

Understanding UPSC Prelims Marking Scheme

The UPSC Prelims consist of two objective-type papers: General Studies (GS) Paper I and Paper II (CSAT). The details of the marking scheme is mentioned below:

  • GS Paper I (200 Marks):
    • Each correct answer fetches 2 marks.
    • 1/3rd of a mark is deducted for every incorrect answer (negative marking).
  • CSAT Paper II (200 Marks):
    • Each correct answer earns 2.5 marks.
    • Negative marking deducts 0.83 marks for every wrong answer.

Understanding UPSC Negative Marking

The UPSC Prelims consist of two objective-type papers: General Studies (GS) Paper I and CSAT Paper II. While attempting these papers, remember that there’s negative marking for incorrect answers. This means marks are deducted for incorrect attempts. Here’s a breakdown:

GS Paper I (2 marks per question): One-third (0.66) of a mark is deducted for every wrong answer. CSAT Paper II (2.5 marks per question): A little less than one-third (0.83) of a mark is deducted for every incorrect answer.

Manually calculating marks and deductions for negative markings can consume precious study hours. Our UPSC Prelims Marks Calculators offer a time-saving alternative. Simply enter the number of correct and incorrect answers, and our calculators will generate a detailed breakdown of your score, including a visual pie chart, in a matter of seconds. This allows you to efficiently evaluate your performance and refocus your efforts.

Remember, this calculator is for estimation purposes only. The official UPSC cut-off marks are declared later. However, it’s a valuable tool to get a preliminary sense of your performance and strategize for the Mains exam.

  • Is a calculator allowed in the UPSC CSAT Exam?

    As per the Union Public Service Commission (UPSC) guidelines, calculators are not permitted during the Civil Services Examination (CSE) Prelims. This prohibition extends to all subjects and question types within the Prelims stage.

    To ensure success in this competitive exam, it is recommended that candidates develop strong mental calculation and estimation abilities. Proficiency in these areas will allow for efficient handling of objective type questions without dependence on a calculator. The UPSC emphasizes the assessment of a candidate's core knowledge, aptitude, and problem-solving skills, and the Prelims format reflects this focus.
