FAQs

What is the syllabus of UPSC in Electrical Engineering?

Electrical Engineering focuses on candidates' understanding of basic concepts and application of knowledge. This subject covers Analog and Digital Electronics, Power Systems, Microprocessors, and other topics.

Can I do UPSC after Electrical Engineering?

Yes, you should pursue Electrical Engineering as an elective for UPSC. The syllabus and question pattern of IES are similar to those of UPSC, and once you have thoroughly covered your syllabus, you can qualify both exams with ease.

How to prepare UPSC optional Electrical Engineering?

Solve previous year's question papers for both Civil Services optional and Engineering Services. Do not overlook numerical issues at any stage. Solve it in conjunction with the theory papers.

Is UPSC easy for engineers?

The CSAT includes questions on reasoning, English comprehension, quantitative reasoning, and analytical reasoning. Engineers typically score higher on the CSAT than humanities graduates because of their scientific expertise.

Which engineering branch is best for IAS?

Both branches are equally significant and rely on one another. I advise you to major in civil engineering because you want to be an IAS official. No other Engineering stream is as helpful for becoming an IAS officer as these branches.
