Dear aspirant !
Hope you are doing great ! Getting failure again and again can depress anybody undoubtedly but you have to do hardwork from now . Posting and asking questions here will not enough , success takes time ,great things come to great people ,become great by doing hardwork . No shortcut is there.  And it is not a big deal to pass the class 11th , firstly forget the past immediately , now starting with first chapter ,with no backlog ,whatever is your query ask to your teacher immediately , don't depend on tomorrow ,make your own shorts note ,devote 6 hours daily ,i said daily ,being consistent is most important in studies , solve previous year and easily you will pass your 11 th class with good marks .
Hope it helps you !
Thanking you
