How to Prepare for Kerala PSC Assistant Engineer Electrical Exam 2026 – KSHB AE

1. Start with high-weightage modules like Electrical Machines, Power Systems, and Power Electronics, since these form the core of Electrical Engineering and are frequently tested.
2. Build strong fundamentals in Electric Circuits and Magnetic Circuits since these topics form the base for advanced concepts asked in Machines and Power Systems.
3. Practice numerical problems regularly, especially in Control Systems, Signals and Systems, and Circuits, as these are calculation-intensive.
4. Revise Digital Electronics and Microprocessor basics thoroughly, since 8085 architecture and number systems are common scoring areas.
5. Don’t ignore application-based topics like Transducers, Batteries, and Electrical Wiring, as these are often overlooked but carry equal marks.
6. Solve previous year KPSC Electrical Engineering question papers to understand the difficulty level and recurring question patterns.
7. Keep a separate short-notes register for formulas (especially in Circuits, Control Systems, and Power Systems) for quick last-minute revision.
8. Take regular mock tests to build speed and accuracy for the OMR/Online exam format.
