📚 SSC JE 2025 Syllabus Explained in Detail

Your Complete Guide for Civil, Mechanical & Electrical Streams

The SSC Junior Engineer (JE) Examination 2025 is one of the most sought-after exams for diploma engineers across India. The exam aims to test candidates on three fronts:
✅ General Intelligence & Reasoning
✅ General Awareness
✅ Technical paper in the respective engineering discipline (Civil, Electrical or Mechanical).

---

🧠 Paper 1: General Intelligence & Reasoning

This section checks your logical and analytical ability. It includes both verbal and non-verbal reasoning.

Topics include:

• Analogies, similarities & differences

• Spatial visualization & orientation

• Problem-solving, analysis, judgment & decision-making

• Visual memory & discrimination

• Relationship concepts

• Arithmetical reasoning & number series

• Classification (verbal & figure)

• Handling abstract ideas, symbols & logical functions.

🌏 Paper 1: General Awareness

This section evaluates your awareness of the environment around you, day-to-day observations, and current events.

Focus areas:

• Indian & world history, culture, geography

• Economic scene, general polity (including Indian Constitution)

• Scientific research & developments

• Questions are framed so that special study is not needed, but keeping up with newspapers & magazines helps.
