HSSC Group D Study Notes 2026: What to Study and How to Revise
Short notes, error logs and a revision schedule built around the HSSC Group D CET syllabus and the Haryana GK section.
Good HSSC Group D notes are short, organised by subject and easy to revise in the last weeks. The CET syllabus is broad, with six areas in one paper, so notes that are too long defeat their purpose. The aim is a compact set you can read many times, not a second textbook.
This page shows what to include for each subject, how to organise your notes and when to revise them.
What to include, subject by subject
Subject | What to note down |
|---|---|
General Awareness | Key dates and events in Indian history, constitutional articles and bodies, rivers and regions, art forms, and a one-page summary of school science |
Reasoning | Patterns for series, coding-decoding and blood relations, plus quick methods for each type |
Quantitative Ability | A formula sheet for percentage, ratio, profit and loss, interest, time and work, and mensuration |
English Language | Grammar rules, common errors, idioms and a word list of synonyms and antonyms |
Hindi Language | Grammar rules, sandhi and samas tables, muhavare and lokoktiyan, one-word substitutions |
General Knowledge of Haryana | A dedicated file on history, geography, economy, culture, personalities and monthly current affairs |
How to organise your notes
Short notes: Keep each topic to one page, in your own words.
Formula sheet: Put every maths formula on a single sheet you can read in ten minutes.
Error log: After each mock, write the topic, the mistake and the right method.
Haryana file: Keep a separate file, since this section carries 25% of the paper, and add to it every week.
Monthly current affairs: Make one page a month for state and national events, and revise the last three months together.
Revision schedule
Same day: Read the day's notes once in the evening.
End of week: Revise all notes from the week, and test yourself without looking.
End of month: Revise the formula sheet, the error log and the monthly current affairs together.
Final two weeks: Read only short notes, the formula sheet and the error log, and attempt mocks.
Reliable sources
Start with the official syllabus on the Commission's website, and school textbooks up to Class 10 for science, maths, history and geography. For Haryana topics, use state government publications and reliable news reports. Do not trust notes that give dates or vacancy numbers without naming the official notice.
