UPSC Prelims Syllabus The UPSC Prelims examination is basically conducted for the purpose of screening only, meaning that the marks that you receive in the Prelims exam will decide your eligibility to appear for the UPSC Mains exam. Also, your Prelims marks will not be considered in your final order of merit, provided you manage to make it through to the interview round. The UPSC prelims examination comprises 2 papers, namely the General studies paper and the CSAT paper or the Civil Services Aptitude Test. Both of these papers have objective-type questions. This GS paper or paper 1 is designed to test your overall knowledge about your surroundings and the world, and also to test how observant you are as a person, by asking questions related to current affairs. The paper contains 100 objective-type questions. Each right answer would fetch you 2 marks, whereas selecting the wrong answer will cost you 1/3 of those 2 marks, or in other words, 0.66 marks will be deducted for every wrong answer. Any question that you choose to leave unanswered will not cost you any marks. The UPSC prelims syllabus for the GS paper consists of topics from a wide range of subjects making it extremely difficult to pinpoint the kind of questions that might be asked in the upcoming paper.
