Hello Bhimesh!

The previous year cutoff of LNMIIT for CSE was 116 marks in JEE. As you have stated that you secured 3800 rank which signifies approximately 117-119 marks. So getting CSE branch in LNMIIT will be based on the level of competition and some luck factor( most probably you will be alloted CSE in first or second counselling). You can opt for CSE branch as the first priority in the counselling form. And LNMIIT offers Communication and Computer Engineering , Electronics Engineering and Mechanical Engineering. You can opt for CCE as your second option. The curriculum offered for CSE and CCE is a lit bit different only(here is the link where you can compare the curriculum - https://www.lnmiit.ac.in/Academic/Undergraduate.html ). LNMIIT also offers some scholarship for which you can apply at the time of admission. If you have scored JEE advance rank upto AIR 12000 then your academic fees will be relaxed( https://www.lnmiit.ac.in/admissions/ugadmissions/Scholarship_Policy.html ).
