EIL Paper on 06th April 2008 at KOLKATA
Hi everybody !!!!!
Recently I appeared for the EIL FROM Electrical branch the paper which included 150 questions around which I attempted for 90 -95 questions.
Negative marking was not mentioned
Total questions:-150 – 2 Hrs.
Technical- 100 questions
Quantitive apti+gen awareness+logical reasoning+intelligence -50 questions
Technical part was ok and the questions mainly came from electrical engineering objective type book by M.Handa and A.Handa They mainly concentrated on power system topcs and the questions from the book of power system by soni , gupta, bhatnagar (Dhanpat rai publications) matched there.
For the apti part it was from the G.K books And some recent news and happenings from Newspapers
