Now, come to Exam pattern.....
The pattern of the Preliminary examination up to 2010 was based on the recommendations of the Kothari Commission (1979). 

  • It included two examinations, one on general studies worth 150 marks, and the second on one of 23 optional subjects worth 300 marks. 
  • Until 2011, when it was revamped,the preliminary pattern was sustained with only minor changes once every ten to fifteen years.
From 2011 onwards, the preliminary examination, now popularly known as the Civil Services Aptitude Test (CSAT) (officially it is still called General Studies Paper-1 and Paper-2), intends to focus on analytical abilities and understanding rather than the ability to memorize. The new pattern includes two papers of two hours duration and 200 marks each.Both papers have multiple choice objective type questions only. They are as follows:
What is the syllabus of IAS prelims?

The Question Papers (Test Booklets) are set in English & Hindi

UPSC Prelims Syllabus for Paper I – (200 marks)

  1. Current events of national and international importance.

  7. General Science.

UPSC Prelims Syllabus for Paper II- (200 marks)

  2. Logical reasoning and analytical ability.

  4. General mental ability.

Is there any negative marking in upsc ias prelims exam 2020? 

  • In prelims, every question is of 2 marks. So, if a student answers a question correctly then 2 marks will be awarded to him. But there is also a penalty on wrong attempt. For every question marked wrong UPSC deduct one-third of the question’s mark. Since every question carries 2 marks, so penalty for every wrong answer will be 2/3 i.e. 0.67 marks.
  • So, suppose a student attempted 79 questions in the prelims exam. Now if he marks 64 question correctly but 15 question wrong. Then his expected score would be: 64(2) – 15(.67) = 128 – 10 = 118 marks.
  • Student should understand this method of calculating marks correctly. As this will help students in finding how much question they need to attempt to get a particular score.
  • For example, if a student aim to get 120 marks in UPSC IAS prelims then he can have several permutations of the question to be attempted to get those marks.:
  • If he attempted 90 questions than he can afford to marks around 22 question wrong: 68(2) – 22(.67) = 121.33 marks.
  • If he attempted 80 questions than he can afford to marks around 22 question wrong: 65(2) – 15(.67) = 120 marks.
  • If he attempted 70 questions than he can afford to marks around 8 question wrong: 62(2) – 8(.67) = 118.67 marks.
  • It is generally seen that those students who don’t try to estimate, how many question they need to attempt to get a particular score, generally over attempts the number of question which led to large negative marking.
