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.

## Thursday, March 30, 2023

This website provides source material for students preparing for NEA, NTC, PSC, and CANN at levels 3 to 7, including Electrician, Foreman, Supervisor, Assistant Engineer, and Engineer. Below, you can find karnali province loksewa aayog 2079, question papers for Level 5 and Electrical Loksewa Level 5 from 2079. These questions are taken from Loksewa aayog's old question paper for the sub-engineer at level 5.
