General Topics at a glance (Tier-I, Section A)

Engineering subjects in this syllabus

The Board publishes the following subject headings for the post of Assistant Engineer (Electrical). Each is reproduced in full, with every topic heading listed beneath it, in the section above.

Preparation Guidance

Derived strictly from the structure of the official notification:

• General Topics are common to every DSSSB engineering post – General Awareness, General Intelligence & Reasoning, Arithmetical & Numerical Ability and both language papers. Prepare this material once and reuse it across posts.
• Arithmetical & Numerical Ability is a closed list. Work through each enumerated item explicitly rather than assuming general quantitative aptitude coverage.
• Reasoning is verbal and non-verbal. Space visualisation, figure classification and arithmetical number series are separately listed and are commonly underestimated.
• Budget time by subject count. The subject-specific headings above show where the paper weight sits for this post.
• Both languages are examined independently. Hindi and English each test vocabulary, grammar, sentence structure, synonyms, antonyms and correct usage.
• Revise from the topic headings. The official notification lists explicit topic headings beneath each subject, which map directly onto the questions asked.
