Good day, KSSSai It's great to hear that you're considering pursuing an engineering degree in the CSE department. But allow me to offer you some sound counsel. Some facts first. The majority of engineering students choose this branch as their first choice, which results in a very high closing ranking or closing percentile. This is valid not only for NIT or IIT but also for institutions that are regarded as universities. Given your grade point average and ranking, it appears unlikely that you will be admitted to a regular course. If you are truly interested in this course, I would strongly suggest you to apply for a management quota seat. I wish you well.

Both CSE and ECE are good options but it is better to opt CSE only if you are really interested in Software field because after completing B.Tech in ECE or in any other branch you can easily come to software field but you cannot enter any other core departments if you are a CSE graduate. Since you want to do M.Tech in Nuclear Engineering my suggestion is to opt ECE because it provides practical learning and lets you be prepared for your Masters. I don't say CSE doesn't provide practical learning but I say it doesn't need because maximum subjects are theoretical and doesn't require any practical knowledge to clear those subjects and that can take you away from learning things practically.
