First....those students who r in 11 and 12....they visit this community ...
after the exams when they get admitted in college...then there is no use of this site for them...if they are not interested in solving question for others.....
Those who r interested they keep their finger stick to this site...
Well i m on this site from second sem ...and i become expert in 3rd sem....now its my duty to solve question submitted by u ( which of course falls in the range my interest and knowledge )...
And a pledge from my side ...i will keep visiting this site..and will keep helping you till this site exist....
