Hello everyone . Nowadays there are numerous you tube channel you tube who takes guarantee for 100% success in clearing a government job exams. You can find more than 100 you tube channels. In between all these we students get confused in choosing a right channel for our exams preparation. In today's time offline coaching are very expensive and students living in villages and towns where proper coaching are not there to teach them.

So for those students you tube platform is the best study center for all those who can't afford to pay such a huge fee to gain their one seat for government job.
According to my point of view among numerous channel , there are few you tube channels where one can study systematically.
Unacademy 
1) Wifistudy
2) Exampur
3) Mahendra guru
 All of them has a very high class faculty and executes a systematic study. 
They all provide PDF and study material and various quizzes to enhance one's speed of solving a question.
I recommend to all students if you don't wanna waste time in offline coaching.
Then sit inside your room ask your parents to switch a WiFi connection and take a pricefull classes.
