# Mr Electro

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.

1. Show me ans

1. Sir you can check how many right answer you have done for now date... We will going developing for other features.

2. How can we check our answers ???

3. How to get results
