UPSC Prelims Examination Guidelines (General Overview)

UPSC Prelims Examination Guidelines (General Overview)

The Prelims consists of two objective-type papers:

  • Paper 1: General Studies (GS)
  • Paper 2: Civil Services Aptitude Test (CSAT)

Both papers are held on the same day with a break in between. Candidates must appear for both papers; failure to attend either disqualifies them from further stages. Importantly, CSAT is qualifying in nature (minimum 33% required), but the Paper 1 score alone is used to determine selection for Mains.

STRATEGIC APPROACH FOR PAPER 1

  1. Categorization of Questions

    During the exam, categorize questions into three types:

    1. 100% Known Questions (~40 Questions)
      • You are certain of the answer.
      • Strategy: Mark and bubble these questions immediately.
      • Time Goal: ~40–45 minutes.
    2. 100% Unknown Questions (~15–20 Questions)
      • You have no idea about the answer.
      • Strategy: Do NOT attempt.
      • Note these on the last page of the question booklet (usually reserved for rough work) under “Unattempted”.
    3. 50% Known Questions (~40–45 Questions)
      • You're partially confident, or the answer might be recalled after a second look.
      • Strategy: Mark these for review. Go back after attempting 100% known.
      • List them as “To Be Revisited” in rough space.
  2. Solving 50% Known Questions – 3-Step Methodology

    Once done with confident questions, revisit the 50% known ones using the following strategies:

    1. Elimination Method
      • Identify and eliminate obviously wrong options.
      • Often narrows down to 50-50. Choose the more probable one.
    2. Repeated Reading + Layered Guessing
      • Read the question multiple times.
      • Allow your subconscious knowledge layers to guide you.
      • Not random guessing — use “informed intuition.”
      • Limit guessing to a MAXIMUM of TWO questions.
    3. Interconnection Between Questions
      • Sometimes, one question contains hints or direct answers to another.
      • Scan for such connections and cross-reference.
  3. Time Management by Question Type

    Questions in the paper vary in terms of length and complexity:

    • Short Questions:
      • Easy to read and comprehend.
      • Reading Time: ≤30 seconds
      • Strategy: Attempt quickly to save time.
    • Medium-Length Questions:
      • Moderate complexity.
      • Reading Time: ~45 seconds
      • Strategy: Prioritize after short ones.
    • Lengthy Questions:
      • Take >45 seconds to read and understand.
      • Strategy: Keep for last if time permits, unless you are confident.

    This classification helps manage time efficiently and avoid bottlenecks.

Pre-Exam Mindset and Best Practices

The day before and on the day of the exam, follow these suggestions:

Do’s :

  • Stay calm, stay composed — stress drains mental clarity.
  • Sleep well the night before the exam — at least 6–7 hours.
  • Reach the exam center well before time.
  • Carry necessary documents (Admit Card, ID Proof).
  • Use your rough page wisely — for question classification and elimination tracking.
  • Trust your preparation and remain focused.

Don'ts :

  • Avoid last-minute cramming — it creates confusion.
  • Stay away from social media distractions.
  • Do not discuss with peers about preparation before entering the hall.
  • Do not panic if the paper feels tough — it’s the same for everyone.

The UPSC Prelims is as much a test of knowledge as it is of strategy, composure, and time management. It is crucial to approach it methodically:

  • Attempt only those questions you’re sure of or can intelligently deduce.
  • Use the rough page for tracking and categorizing.
  • Focus on accuracy — avoid random guesses.
  • Develop your ability to use knowledge layers, eliminate options, and identify interconnections.

Prepare smartly, stay positive, walk into the exam hall with confidence — and success will follow.

All the best!
