UPSC aspirants with Electrical Engineering appears in IAS and IES both exams. Both are very tough and needs to be prepared with the right books and proper strategy. Mains Syllabus is almost the same for both. Aspirants are advised to check old question papers of both exams to have the clear idea of the level.
