Hello Aspirant,

With a rank of 6343, you definitely have a high chance of getting ECE in Techno (Main Campus). You might also get ECE in Heritage if you're lucky however historic data suggests cutoff for ECE in Heritage to be approximately 5800. Talking about IEM, it is extremely difficult to get into with ECE.

Your first question wasn't very clear, but assuming you want CSE in any college, then yes there are many other colleges where you will get CSE with this rank.

Hope it answers your question.
