Syllabus

Technical Abilities (Electrical) is close to the SSC JE Electrical list: basic concepts, circuit laws, magnetic circuits, AC fundamentals, measurement, electrical machines, synchronous machines, generation, transmission and distribution, estimation and costing, utilisation of electrical energy, basic electronics. The CEN has the exact list.

How to prepare (free, in order)

  1. Prepare the SSC JE technical syllabus (SSC JE page). It covers most of the Technical Abilities section.
  2. CBT-1 is diploma-level maths, reasoning and science. School NCERT science (Class 9–10) is the free base.
  3. For CBT-2, add the short computer-basics and environment sections. They are 20 easy marks.
