B.Tech

As you have understood most of the concepts of C Programming in your 1st year, then it's a good idea to begin with either Data Structures using C or Object Oriented Programming using C+ by yourself. The reason is you'll have to study this and OOPS in your 3rd and 4th semester of B.Tech. So, it's better to begin early, you will have better understanding of the concepts and when your professors will teach you, you'll get more clarity in your learnings and this will eventually help you to score a good percentage in your exams too. If you want to get access to programs of all programming languages taught in entire B.Tech Course (CSE or IT), you can get them from this app "B.Tech CSE & IT Course Programming" which is specially developed for B.Tech students available on Google Play Store.

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.

If you'll start early, it'll be beneficial for you only. Begin from your 1st semester, as professors will already be teaching you the basics of programming. So, it's better to start off with them, so you can clear your doubts and queries with them on timely basis and it'll not clutter up. Almost every other college teaches C as the first language, so it's better to begin with C. In this way, you'll also stay up-to-date with your syllabus and course's curriculum. If you're starting on your own then you can follow books, videos, websites, and courses to understand the concepts of C, there are plenty of them available online. If you want to get access to the programs of all languages including C, C+, Java & SQL, then you can follow this app, which is specially developed for B.Tech students.

According to me, go with B.Sc in Physics, The Department of Applied Sciences at The NorthCap University offers a wide range of courses in the areas of Physics, Chemistry and Mathematics to build a strong foundation of students as a part of engineering education. The Department also offers undergraduate and postgraduate programs in basic sciences. They educate a diverse group of students through a blend of rigorous and project-based curriculum and adopting unique teaching methodologies. Basic Sciences form the backbone for knowledge development not only for scientists but also for engineers. The focus is to produce scientists and engineers equipped with modern scientific tools with a strong understanding of real-world and engineering problems. Visit: https://www.ncuindia.edu
