Hello Friends, I am Sudhanshu Chaudhary. I have secured AIR-139 in GATE-2017 and qualified ESE Written twice. Alongwith my B.Tech studies and Preparation, I developed an interest in Teaching i.e. I liked to share my knowledge with everyone, but I didn’t wanted to pursue teaching as my career and for that LGF is the best platform. Also I have seen that there is very less free of cost content available on Internet for ESE/GATE oriented studies. So i started to give you the free lecture on those subject in which i am expert like communication system. I have been a part of LGF facebook group since my preparation days. Here numerous times we have shared our knowledge and did fruitful discussions. So to follow my interest and to contribute to society, I choose to be a part of LGF.You can tag me anytime if you have any query regarding this subject. I will try to resolve you query. For doubt solving you can join our facebook group (Learn GATE Free). All the best and happy studying.
