Multiple Choice Questions (MCQs)

The UPSC (Union Public Service Commission) Prelims exam is the first step in the selection process for the Indian Administrative Service (IAS), Indian Foreign Service (IFS), and Indian Police Service (IPS) among other civil services in India. The exam consists of two papers: General Studies Paper 1 and General Studies Paper 2 (also known as the Civil Services Aptitude Test or CSAT). The General Studies Paper 1 is worth 200 marks and is comprised of multiple choice questions (MCQs). The exam tests the candidate's knowledge of current events, Indian and World history, Indian and World geography, Indian polity and governance, economic and social development, general science and environmental ecology and biodiversity.

The UPSC Prelims exam is a highly competitive exam and it is important for candidates to have a thorough understanding of the syllabus and to practice as many MCQs as possible to increase their chances of success.

You will have to answer all the questions within a limited time frame. So practice time management techniques and use a timer while solving mock tests.

The questions are designed to test the candidate's understanding of the subject matter and their ability to apply that knowledge in a practical context. So, MCQs on this website are prepared in that direction to make you conceptually strong.

The MCQs in UPSC Prelims are generally of the following types:

  1. Factual: These questions test the candidate's knowledge of basic facts, figures, and dates.
  2. Conceptual: These questions test the candidate's understanding of concepts and principles.
  3. Analytical: These questions test the candidate's ability to analyze and interpret information.
  4. Applied: These questions test the candidate's ability to apply their knowledge to practical situations.
  5. Current events: These questions test the candidate's knowledge of recent events and happenings.
