No ra..it's not possible!!

Don't think iam demotivating you.......preparation for iit requires extreme hard work and commitment for 4 years...ie right from ur 9th and 10th..then 11,12.Those who have a strong foundation in 9th and 10th only can excel in theit 11th and12th iit prep and get qualified...Most of us start prep from 11th with cbse board ...and with too many dont make...and i ur case with sateboard it makes it almost impossible..concentrating on this idea may spoil ur prep for boards and at the end u may end up getting nuting...iam not harsh or discouraging ....but its the fact ..study well in ur boards and try to get top marks and u can get into anna univ,psg tech etc...

if ur still interested then u may prepare for aieee .....get both 11th and 12th physics chem cbse books and read and try to understand the concepts well....join a par time aieee coaching and u may qualify aieee.but my best advice is u concentrate a lot in ur boards.
