How to Prepare for SSC CGL in 3 Months

A complete roadmap to crack SSC CGL with a focused 90-day strategy. Covers Tier-1 and Tier-2 syllabus breakdown, daily schedule, and best resources.

SSC CGL 2025 drew 28 lakh applications for about 14,500 posts. Most of those candidates never finish the syllabus. Three months is enough for Tier-1 if you stop collecting resources and start solving questions on day one.

Know the paper before you study

  • Tier-1: 100 questions, 200 marks, 60 minutes. Four sections of 25 questions each: Reasoning, General Awareness, Quantitative Aptitude, English. Negative marking is 0.50 per wrong answer.
  • Tier-2 Paper-1 is the one that decides selection: Maths (30 q), Reasoning (30 q), English (45 q), General Awareness (25 q), Computer (20 q). Each question carries 3 marks, minus 1 for a wrong answer.
  • Only Tier-1 is qualifying for most posts; your Tier-2 score is what gets ranked. Prepare for Tier-2 from the start.

Month 1 — build the base

  • Maths: finish Arithmetic first (percentage, profit and loss, ratio, time and work, speed-distance, SI/CI). These are 60% of the paper and the fastest to score.
  • English: 30 minutes a day on grammar rules (subject-verb agreement, tenses, prepositions). One passage of reading daily.
  • Reasoning: practise 50 questions a day from previous-year papers; most patterns repeat.
  • GA: start a current-affairs notebook from today and revise it weekly. Static GK comes from previous-year questions, not textbooks.

Month 2 — speed and coverage

  • Maths: Advanced topics now (Geometry, Trigonometry, Mensuration, Algebra). Learn the 20 standard results, then solve 40 questions a day under time.
  • English: vocabulary from previous-year papers (one-word substitution, idioms, synonyms). Start one full English sectional every other day.
  • Take one Tier-1 full mock every Sunday. Analyse every wrong answer the same day.

Month 3 — mock and revise

  • One full mock a day, alternating Tier-1 and Tier-2 pattern. Target 150+ in Tier-1 and 80% accuracy.
  • Stop learning new topics after day 75. Revise formula sheets, error log, and current affairs.
  • In the last week, sleep on time and solve only easy and medium questions to protect accuracy.

Daily schedule that works

Six hours is enough if they are focused: 2 hours Maths, 1.5 hours English, 1 hour Reasoning, 1 hour GA, 30 minutes revising yesterday’s mistakes. Working candidates can split this across morning and night; the Maths block must stay daily.
