Dear student,

You haven't mentioned your class. But if you are in 12th standard then you have very less time with you, start right now, first of all make a daily target of completing the video lectures. If each video is if 3 hrs for example then complete atleast 2 videos daily. And increase your potential day by day. Do not procrastinate yout work and be disciplined. If you are in 11th standard then you still have time, you can do this. Just think about the time when you would have cracked jee, think about that moment and your happiness and just strive to achieve that.
