i have passed my 12th board this year.but i have failed in maths.since i took six subjects in total so cbse has declared me a passed candida

here u have faced a major problem as maths is a basic requirment for bca, bsc , btech courses...now its only dependable on the particular colleges...if they can give u admission in bsc,..but u can give maths xam again to get passed.. there may be a procedure to give it again

for this check the details through college where you want to get admission. they may or may not include marks of maths for admission in B.Sc IT
