ISC board strictly follows best of 4 rule with English as an compulsory subject. I am also a ISC passed out student and i have got a percentage guidelines certificate issued from my school. 

JEE does not require any 12th percentage because when we appear in JEE our 12th results are not declared. So it does not matter but in counselling you will need to feed your result

hello radhika

as far as eligibility of josaa is concerned it is 75% for all five subjects or you have to be in top 20 percentile for any board if not 75%.

Hi Radhika,

To be eligible for admissions, a candidate must have scored 75%( for SC/ST/PWD there is a relaxation of 10%, ie they must have scored 65%) in his/her board exam or must be in top 20 percentile of that board.

So, to answer your question you must have 75% in all the five subjects.

All the best
