Yes, you can get into it with these scores. The eligibility criteria to get admission in BTech ECE is just to have 45%in 12th with PCM also with a minimum of 45% marks in each subject and should have cleared JEE mains with valid scores and rank. JEE mains marks are considered for the admission round. All students were categorized and listed in a particular manner based upon their overall score of 12th and JEE according to which they are called for their branch choices. Simply it is like a student with good marks are preferred first, they get the chance to chooses their desired branch. We have 4 branches in UG BTech with a maximum intake of only 60 students. So if the ece branch is full before announcing your name, you may not get admitted to ECE. But surely you can have other branches.
Good Luck to you!
