SSC JE Topics 2026
High-yield topics by subject and what to study first.
Updated 22 October 2026
High-yield topics for SSC JE
General Engineering carries the most marks in Paper 1 and all of Paper 2, so technical preparation decides selection. Reasoning and GA are useful for scoring in Paper 1.
Civil and Structural
- Building materials and concrete technology
- Surveying and levelling
- Soil mechanics
- RCC and steel design
- Hydraulics and fluid mechanics
- Estimating and costing
Electrical
- Network theorems and AC circuits
- Electrical machines (DC, transformer, induction, synchronous)
- Measurements and instruments
- Power systems: generation, transmission, protection
- Utilisation and estimation
Mechanical
- Thermodynamics and IC engines
- Strength of materials
- Fluid mechanics and hydraulic machines
- Theory of machines
- Production engineering
General sections (Paper 1)
- Reasoning: analogy, series, coding-decoding, non-verbal
- General Awareness: polity, history, science, current affairs

Suggested preparation order
- Revise core subjects of your branch from diploma/degree notes and standard books.
- Solve previous year JE questions subject-wise – many concepts repeat.
- Build Reasoning and GA in parallel in small daily slots for Paper 1.
- Practise Paper 2-style questions with the +3 / −1 scheme; attempt only when confident.
- Take full-length mocks for both papers and track weak topics.
