Step-by-Step Preparation Plan
Step 1: Know the Pattern and Previous Papers
Download the latest notification and syllabus. Solve one or two previous year papers to understand difficulty and time pressure.
Step 2: Build Basics (First 6 to 8 Weeks)
Revise school-level maths and basic reasoning. Learn tables, squares and cubes. Start reading a newspaper and make a list of new words. Learn basic grammar rules.
Step 3: Practice and Speed (Next 8 to 12 Weeks)
Solve topic-wise questions every day. Take sectional tests and track accuracy. Practise General Awareness with short quizzes and revision notes.
Step 4: Mocks and Revision (Last 6 to 8 Weeks)
Take full-length computer-based mocks two to three times per week. Analyse each test and fix weak areas. Revise formulas, important facts and your error notebook.
Subject-wise Strategy
Quantitative Aptitude
Start with arithmetic basics: percentages, fractions, ratio and proportion, average and profit and loss. Practise time and work, speed and distance, and simple and compound interest. Learn basic geometry and mensuration formulas. Work on calculation speed with tables and squares, and solve mixed problem sets in timed conditions.
Reasoning
Reasoning is scoring with practice. Learn patterns in series, analogies and classification. Practise coding-decoding, blood relations, direction sense and puzzles. For puzzles, draw neat diagrams and write clues clearly. Practise at least one set daily and review your approach.
English Language
Build grammar basics: tenses, articles, prepositions, subject-verb agreement and sentence structure. Read an English newspaper daily, learn five to ten new words with meanings and sentences, and solve one or two comprehension passages. Practise error spotting and fill in the blanks with timing.
General Awareness
Divide into static and current affairs. For static topics, read short notes on Indian history, polity, geography, economy and science. For current affairs, read the news and make monthly notes. Revise weekly with quick quizzes. Our general awareness section and full forms list can help with quick revision.
Typing and Computer Skills
- Practise typing on a computer every day for 15 to 30 minutes.
- Use a typing tutor or online typing practice to improve speed and accuracy.
- Learn basic keyboard shortcuts and MS Office functions.
- Practise typing text in English (and Hindi if required for the post).
- Check the notification for the required speed and the test format.
Typing is a skill that improves steadily with regular practice, so do not leave it for the last month.
Daily Timetable Example
| Time | Activity |
|---|---|
| Morning (1.5 hrs) | Quantitative Aptitude: concept plus 25 to 30 questions |
| Late morning (1 hr) | Reasoning sets |
| Afternoon (1 hr) | English: grammar, vocabulary and comprehension |
| Evening (1 hr) | General awareness and current affairs |
| Night (30 min) | Typing practice and revision |
If you are studying or working, reduce the hours but keep the same order. Weekends are for mocks and analysis.

Health, Motivation and Time Management
Long preparation can be tiring. Sleep 7 hours, eat regular meals, exercise lightly and take one rest day each week. Break your goals into weekly targets and celebrate small wins. Avoid comparing your progress with others. If you feel stressed, talk to a friend or mentor. Read our guide on effective study methods for useful habits.
Backup Options
Because vacancies are limited, keep a backup plan. Prepare for other exams with similar syllabus such as SSC CGL, banking, railways and state exams, and build skills like computer knowledge and communication. Read our careers section for ideas.
