For a UPSC CSE aspirant, the optional subject is also an important subject. In the UPSC mains exam, optional marks have two papers, Paper 1 and Paper 2. Each paper is of 250 marks which makes a total of 500 marks. The UPSC optional subject list contains 48 subjects in total, one of which is Electrical Engineering.

• This subject syllabus mainly focuses on the candidates’ understanding of the basic concepts and application of knowledge.
• Students who have studied Electrical Engineering in their graduation can choose this as an optional subject.
