Recommended Syllabus for EKT Exam of AFCAT for Mechanical Engineering
Guys if you are thinking of finding any official syllabus for EKTexam then please stop, Board has not declared any official syllabus for EKTexam, every site has prepared syllabus on observation basis and claim to thiswill be devoided. You can find the syllabus for EKT exam for Mechanical Branch.EKT exam are given by those who have qualified AFCAT exam and opted Technicalbranch.
If you are having good knowledge of your field then you need notto worry for that you will clear it easily it is not so hard as you arethinking.
And Engineers have special capabilities everyone knows it, i don’twant to mention. I have provided a post regarding:
Complete overview, Purpose, Process and Preparation Tips for EKTExam please read it also.
