how much time does one need to study daily in order to clear jee??????????

Hi
Well it does depend on the capacity of the person and his concept grabbing power.
But since you are asking i'll tell you "NOT TO WASTE" time in those two years.
When you feel like you are wasting your time will mean you haven't given enough time to JEE preparation.

There is no such specific time.. Be serious in your coaching classes and just self study for 3-4 hours maximum per day.. It is enough.. Understanding your concepts is more important.. some take more time to study the same chapter, some less.. It depends on you
Thanks
