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.

NEA LokSewa Test || Model question set 1

This is a sample question paper which is just test your knowledge in Mr. Electro which is very useful for jobs in NEA, NTC, PSC, CANN for level 3, leve 4, level 5 and level 7.
This is set 1 for you. Please share it with your friends that will helps us to make more questions set for you.
