7. Preparation Strategy

6-Month Study Plan

Month 1-2: Foundation + Physical Fitness

• Start your physical training immediately — running, long jump, high jump practice daily. Physical fitness takes time to build
• Begin with Mathematics basics — Number System, Percentage, Ratio, Profit-Loss
• Read one newspaper daily and note down current affairs
• Get familiar with the exam pattern by solving 2-3 previous year papers

Month 3-4: Subject Mastery

• Complete General Studies — focus on Indian History (Modern India), Indian Polity, and WB GK
• Complete Reasoning section — practice daily for speed and accuracy
• Continue physical training without gaps
• Start practicing descriptive answer writing for Mains (Essay, Precis, Translation)

Month 5-6: Mock Tests + Mains Prep

• Take 15-20 full-length Prelims mock tests under timed conditions (90 minutes)
• Practice Mains-style essay writing and precis at least 3 times a week
• Revise all subjects — focus on your weak areas
• Compile 6 months of current affairs and revise them thoroughly
• Maintain physical fitness — increase intensity closer to PET date

Subject-wise Tips

• General Studies: Modern Indian History and Polity are the highest weightage areas. Bengal-specific questions are common — learn key events, personalities, and places.
• Mathematics: Focus on speed. Learn shortcut methods. Time-Work and Speed-Distance are the most asked topics.
• Reasoning: Daily practice of 20-30 questions is the best approach. Focus on Coding-Decoding and Series.
• English (for Mains): Practice essay writing weekly. Read editorials for better vocabulary and sentence construction.
• Physical Fitness: Start running practice from day one. Many candidates clear the written exam but fail in PET. Do not neglect physical preparation.

Common Mistakes to Avoid

• Focusing only on written exam and ignoring physical preparation — this eliminates many candidates
• Not practicing descriptive writing for Mains — it is very different from MCQ preparation
• Random guessing in Prelims — with 0.50 negative marking per wrong answer, this can be costly
• Underestimating the Personality Test — 8 out of 30 is the minimum, but scoring well here can make or break your rank
