If you want a central government job straight after Class 12, the Staff Selection Commission's Combined Higher Secondary Level (CHSL) exam is open to you with just a 12th pass. Here are its posts, its two tiers and a 26-week plan for a complete beginner. The rules come from the SSC CHSL 2026 notice; they can change each year, so read the current notice on ssc.gov.in before applying.
What posts does SSC CHSL offer after 12th?
According to the 2026 notice, CHSL fills Group C posts in central ministries, departments and constitutional bodies:
Lower Division Clerk (LDC) or Junior Secretariat Assistant (JSA): Pay Level-2 (Rs 19,900-63,200).
Data Entry Operator (DEO): Pay Level-4 (Rs 25,500-81,100) or Level-5 (Rs 29,200-92,300).
DEO Grade 'A': Pay Level-4 (Rs 25,500-81,100).
The 2026 age limit was 18 to 27 years on 1 August 2026, with 5 extra years for SC/ST and 3 for OBC candidates. Any 12th pass qualifies for most posts, but DEO posts in the Ministry of Consumer Affairs, Food and Public Distribution, the SSC and the Ministry of Culture need 12th Science with Mathematics. The fee was Rs 100; women, SC, ST, PwBD and eligible ex-servicemen paid nothing. These posts carry All India Service Liability: you can be posted anywhere in India.
How do the SSC CHSL Tier-I and Tier-II exams work?
Under the 2026 notice's scheme of examination, Tier-I has four parts of 25 questions each: English Language, General Intelligence, Quantitative Aptitude (basic arithmetic) and General Awareness. Each part carries 50 marks, the paper takes 60 minutes, and every wrong answer costs 0.50 marks. The minimum qualifying marks are 30% (unreserved), 25% (OBC/EWS) or 20% (others), but the Tier-II shortlist is drawn on merit.
Tier-II runs in two sessions on the same day:
Section-I: Mathematical Abilities and Reasoning, 60 questions in one hour.
Section-II: English Language and Comprehension (40 questions) and General Awareness (20), in one hour.
Section-III: Computer Knowledge, 15 questions in 15 minutes, qualifying only.
Section-IV: a typing test for LDC/JSA or a skill test for DEO, qualifying only.
Each Tier-II question carries 3 marks, and a wrong answer in Sections I to III costs 1 mark. You must clear every section; Sections I to III use the same minimums. For LDC/JSA, the typing test asks for 35 words per minute in English or 30 in Hindi over 10 minutes, with Hindi typed in the Mangal font. DEO candidates need 8,000 key depressions per hour (15,000 for the DEO posts that require Science with Maths).
What does a six-month SSC CHSL plan look like for a beginner?
This plan follows the topic lists in the notice's indicative syllabus and assumes about three hours of study on weekdays.
Month 1 (weeks 1-4), find your level. Take one full Tier-I-style paper under the clock. Rebuild number systems, percentages, ratio and averages. In English, start on spot-the-error, voice and narration. Type for 15 minutes daily; our guide to learning touch typing as a student has a starter routine.
Month 2 (weeks 5-8), arithmetic and reasoning. Profit and loss, interest, time and work, time and distance. Reasoning: analogies, series, coding-decoding, Venn diagrams. Begin General Awareness with history, geography, polity and economy, plus 20 minutes of news a day.
Month 3 (weeks 9-13), the harder maths. Algebra, geometry, mensuration, trigonometry and data charts. Non-verbal reasoning: figure series, paper folding. English: cloze tests and comprehension.
Month 4 (weeks 14-17), switch to practice. One full Tier-I mock a week plus sectional tests. Cover computer basics: memory, MS Office, email, cyber security.
Month 5 (weeks 18-21), two mocks a week. Review each one the same day with a 60-minute mock analysis routine. Add mean, median, mode, standard deviation and probability, which only Tier-II tests.
Month 6 (weeks 22-26), Tier-II conditions. Keep two full mocks a week under Tier-II marking (plus 3, minus 1), revise from your error notebook, and hold 35 words per minute in English (or 30 in Hindi).
If a Class 10 idea such as similar triangles never made sense, the Fermi Concept Library has a lesson for each concept in mathematics. When you keep getting one type of question wrong for the same reason, the Fermi Problem Library works problems step by step and explains the reasoning rather than printing an answer.
How do you know if the plan is working?
Under the 2026 marking scheme, a Tier-I question is worth 2 marks and loses 0.50 if wrong, so one wrong answer cancels a quarter of a right one. In Tier-II, one wrong answer cancels a third. Every Sunday, check:
Your mock score in each section, not just the total.
Accuracy: of the questions you attempted, what share were right?
Typing speed and error count from that week's best test.
Whether every section clears its qualifying mark.
