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.

Model Question set 4 for NEA, NTC, PSC, CANN

Are you preparing for NEA, NTC, PSC, CANN for level 3, leve 4, level 5 and level 7. If yes? you are in right place.
This is a sample question paper which is just test your knowledge in Mr. Electro which is very useful for jobs.
