The HSSC ECE Trade Syllabus 2026 covers Group 62 recruitment for ECE Trade posts under the Haryana Staff Selection Commission. This HSSC ECE Trade Syllabus guide breaks down the exam pattern and the full subject-wise topic list, straight from the official syllabus published at hssc.gov.in, so you know exactly what to study before you open a single PDF.
HSSC ECE Trade Syllabus Exam Pattern
Group 62 recruitment follows the standard two-stage HSSC process. Stage one is the Common Eligibility Test (CET) — 100 questions, 100 marks, roughly 90–105 minutes, covering general awareness, reasoning, Hindi, English and quantitative aptitude. Clearing CET plus the socio-economic criteria stage qualifies you for the group-specific written exam, which is where the HSSC ECE Trade Syllabus below actually applies.
The HSSC ECE Trade Syllabus for the written exam splits into weighted parts:
- General awareness, reasoning, quantitative aptitude, science, history (including Haryana-related history), current affairs, literature, geography, civics, environment, culture, etc.—20% weightage
- Computer terminology, fundamentals, word software, Excel software, PowerPoint, internet, web browsing, communication, emails, downloading and uploading data on websites, etc.—10% weightage
- Subject-related syllabus — 70% weightage
HSSC notes on the official document that this weightage is tentative and may vary, so treat it as a study-time guide rather than a locked question count.

How to Prepare for the HSSC ECE Trade Syllabus Exam
Start with the subject-specific block of the HSSC ECE Trade Syllabus first — it carries the heaviest weightage and is where real differentiation between candidates happens, since general awareness and computer knowledge sections overlap with every other HSSC group. Work through each topic area systematically, and revisit the subject list above every week so nothing slips through before exam day.
Don’t skip the common portion either. Haryana-specific general awareness and basic computer knowledge are easy marks that candidates often under-prepare because they’re focused on the technical syllabus.
