Hi Mr Electro family!! This is an educational website for electrical stream ( Electrical engineering, Diploma student and PreDiploma students) . This is mainly focused for those students who are waiting for Government jobs like LokSewa Aayog PSC, NEA, CANN NTC for level 3, level 4, level 5 and level 7 and also private jobs.

Syllabus of NEA level 7 || NEA syllabus level 7

This is the Syllabus of NEA level 7 || NEA syllabus level 7 loksewa exam for free quota(khulla quota). This is taken from NEA official website to help others. For more syllabus, you can directly contact us by mail. The NEA syllabus level 5 is given below.
