Union Public Service Commission
which conducts the Civil Services Exam
every year follows a standard exam pattern for the 3 stages,
viz, Prelims, Mains
, and Interview
; after completion of which the board selects the candidates based on their marks and ranks for the varied services like,
Indian Administrative Services (IAS), Indian Police Services (IPS), Indian Foreign Services (IFS)
and other services categories in Group A and Group B.
However, different stages of the IAS exam have different syllabus.
The UPSC Prelims Syllabus focuses on general and societal awareness which is tested by objective-type (MCQ) questions.
The UPSC Mains Syllabus is much more comprehensive as this stage comprises nine theory papers,
and the final interview stages tests the overall personality of the candidate by the competent board members.
Civil Services Exam conducts in three Phases:
- Preliminary Examination (Objective)
- Main Examination (Subjective)
- Interview or Personality Test (Vocal section with Panel of UPSC members)
Phase 1: UPSC Prelims Exam
The UPSC Civil Services Prelims Examination is composed of two components:
1) General Studies
||General Studies (GS)
||2 hours (9:30 AM to 11:30 AM)
||2 hours (2:30 PM to 4:30 PM)
2) Civil Services Aptitude Test (CSAT)
- Broadly, the UPSC Civil Services (Preliminary) Examination consists of two papers of objective type,
each of 200 marks (hence totaling 400 marks) and of two hours duration.
To qualify for the Civil Services Mains, a candidate must attempt both the papers.
- Further, the UPSC General Studies (GS) paper consists of 100 questions, while the CSAT paper consists of 80 questions.
Both papers have negative marks for wrong answers marked to the tune of 1/3rd of the total marks assigned to that question.
- To further illustrate this, each correctly answered GS question will be awarded 2 marks.
So, 0.66 marks would be deducted from the total for every question that is wrongly marked.
- Similarly, in the CSAT paper, since we have 80 questions for 200 marks,
correctly answered CSAT question would attract 2.5 marks each,
while every wrongly marked question would attract a penalty of 0.833 for each such wrong answer,
which will be deducted from the total.
- Questions that are not attempted will not attract any negative marks.
The two papers of the IAS prelims are discussed in detail below:
- General Studies (Generally conducted between 9:30 AM to 11:30 AM)
The General Studies test is the first paper of the preliminary examination.
This test is intended to test the general awareness of a candidate in a wide range of subjects that include:
Indian Polity, Geography, History, Indian Economy, Science and Technology, Environment and Ecology,
International Relations and associated
UPSC current affairs.
- Civil Services Aptitude Test (CSAT) (Generally conducted between 2:30 PM to 04:30 PM)
- This UPSC Prelims syllabus for CSAT intends to assess the aptitude of the candidate in solving ‘Reasoning and Analytical’ questions, apart from ‘Reading Comprehension’
and the occasionally asked ‘Decision Making’ questions.
- The ‘Decision Making’ based questions are generally exempt from negative marks.
- The preliminary examination is only meant for screening a candidate for the subsequent stages of the exam.
- The marks obtained in the Prelims will not be added up while arriving at the final rank list.
