Engineering

I believe you have to have your interest towards coding because that's the only reason you're pursuing your BCA. Without the interest and willingness to code, the BCA degree wouldn't help you that much in your career. The qualities that a candidate can have is to be already aware of programming languages and their logics. If you've already studied programming in your 10+2 then you wouldn't face much difficulties in BCA. It'll be beneficial for you as you'll stay ahead of the competition and will also be able to score good percentage in your early semesters. If you want to learn programming languages which you will be studying in your BCA course then you can check out this app "BCA - Course Programming" which is specially designed and developed for BCA students and is available on Google Play Store. It has programs and assignments of languages like C, C+ and Java with their outputs. You'll be studying these languages in your 3 years of BCA.

No, it is not mandatory to be good or have experience in programming, if you are interested in pursuing CSE. In CSE & IT both, programming languages will be taught from the basics. So, it doesn't matter if you previously had any knowledge/experience in programming or not. Your professors will spend first 2 semesters teaching you the basics of programming including syntaxes, basic input/output, loops, algorithms etc. You can begin learning on your own too from online tutorials, blogs, courses, videos, to get a little grasp on the basics, which will be strengthened when you'll attend your lectures. If you want to get access to all programs/codes of all programming languages taught in entire B.Tech course then you can follow this app "B.Tech CSE & IT Course Programming" on Google Play. It is specially developed for B.Tech students.
