Notes
SSC CGL — Study material for this exam
The quantitative aptitude notes are the ones to start with, and within them, arithmetic before advanced mathematics. Percentage in particular is worth an early week of its own: profit and loss, discount, simple and compound interest and most data interpretation are percentage questions in different clothing, so fluency there pays off across a quarter of the paper.
How to use written notes without wasting the time
- Read a topic once for understanding, then close it and solve twenty questions before re-reading anything.
- Write down only the results you keep forgetting — a formula you remember does not need copying out.
- Revisit a topic three days after you first study it, then two weeks later. Two short revisits beat one long session.
- Move to the next topic when your accuracy is stable, not when you feel confident. The two are different signals.
General awareness deserves a different handling from the rest. It does not reward deep study; it rewards repeated light contact with the same material. One static source revised five times will beat five sources read once, and the same is true of current affairs digests.
- Quantitative aptitude
- The largest and most durable investment. Arithmetic first, to fluency, because Tier 1 leans on it and Tier 2 assumes it. Then algebra, geometry, trigonometry and mensuration, which is where Tier 2 separates candidates. Work problems rather than reading worked examples — the two feel similar and are not.
- English
- A daily habit rather than a subject to be finished. Grammar rules are a closed set and can be learned in weeks; vocabulary and reading speed only respond to repeated exposure over months, which is why starting English late is so hard to recover from.
- General awareness
- Breadth over depth, revision over study. Static knowledge — polity, history, geography, general science — repeats far more reliably across cycles than current affairs does, so weight your time accordingly.
- Reasoning
- The fastest section to convert into marks. Most of what Tier 1 asks is pattern recognition that improves quickly with volume, and non-verbal reasoning in particular rewards practice on paper rather than theory.
- Computer knowledge (Tier 2)
- A small, finite module with no conceptual difficulty. It is fully learnable in a few weeks and is among the highest returns per hour available anywhere in this exam.
The two specialist Tier 2 papers need a separate decision, and it should be made early rather than at the application stage. Paper 2 in statistics and Paper 3 in finance and economics are taken only by candidates applying for Junior Statistical Officer and for Assistant Audit Officer or Assistant Accounts Officer respectively. Each is a genuine additional subject with its own reading, so opting for those posts means adding months of preparation — worth it if the post is what you want, wasteful if you added the preference casually.
On making your own notes
The most useful set of notes in this preparation is the shortest one: a personal sheet of the formulas, rules and facts that you specifically keep forgetting. It grows from your error log rather than from a syllabus, which means it is different from anybody else’s and is the only document worth re-reading in the final week.
What to read for each Tier 1 section, and the depth that is wasted on it. Tier 2 depth differs and is noted where it does.| Section | Read this | Do not spend time on |
|---|
| Quantitative aptitude | One arithmetic source worked to completion, then algebra, geometry, mensuration and trigonometry — which carry far more weight in Tier 2 than in Tier 1. | Advanced or competitive-mathematics material written for engineering entrance papers. The level here is school arithmetic and school geometry, applied fast. |
|---|
| General intelligence and reasoning | A question bank rather than a textbook. Verbal and non-verbal families both appear, and non-verbal is the half banking-focused material omits. | Long theoretical treatments of reasoning. Nothing here has to be learned, only drilled. |
|---|
| General awareness | Static general knowledge organised as pairs, school-level general science, polity, modern history, geography and economy, plus current affairs kept as a monthly consolidation. | Deep subject reading. The questions are single-fact and broad; depth in one subject buys very little across the section. |
|---|
| English comprehension | A grammar reference worked through once, then error detection, sentence improvement and cloze practice. Vocabulary built from reading rather than from lists. | Literature or advanced usage. The paper tests rule application and common vocabulary. |
|---|
| Tier 2 additions | Computer knowledge and the data entry or skill requirement for the posts you are eligible for, plus statistics or finance where your post paper requires it. | Assuming the Tier 1 reading list covers Tier 2. It does not, and Tier 2 is the stage that builds the merit list. |
