Hello,

Board exam score i.e. 12th percentage is eligibility criteria for the college.  JEE mains score/ rank is selection criteria which when comes in range of any branch option you have given in the counselling form, you will get the college offer in the counselling round.

In other entrance exam like KEAM , both 12th and entrance score is considered in equal weight-age to calculate the final score and rank.

for JEE main, NTA calculates your rank from your score and considering other factors to make rank list.

so, to become eligible for SRMIST, 12th percentage is important and to get admission/seat, JEE score/rank is important.

Hope it helps!
