about GATE exam

Dear Sir,
I am an engineering student from INDIA. I want to prepare for "GATE" exam which is accepted many Colleges like IITs, and some of European and Singapore Universities. For the students who were dreaming about pursuing their masters in India or these specified European and Singapore Universities, the GATE exam is mandatory, but now everybody wants to earn money through their businesses but that's not wrong, what i am trying to say is not everyone is working for Society like the way "KHAN ACADEMY" was doing . Your institution was one, who is making our dreams possible by putting your hours into work for us.
It would be a great help if u make a test video series on GATE exam, it will be helpful for the 12 lakhs (1.2million) students "every year". Thank you so much sir, have everything to start earning but the "KHAN ACADEMY" is not charging a single rupee(INR), not everyone can have a Big and pure heart, actually not everyone has time to think about society and students.
special thanks to "S KHAN" sir, it is a great initiative..more success to you. Thanks to every one of the staff present at "KHAN ACADEMY" putting your hours into work for us. Thank you so much entire team.
