I am a JEE aspirant. I have decided to take computer science related courses. But I need a 2nd option other than CSE that has more scope. Can you suggest something?

If you’re looking for another BTech program in the field of Computer Science that isn’t CSE, please consider the new AI and Data Analytics (AIDA) B.Tech program offered by the Wadhwani School of AI at IIT Madras. AIDA is a new program at IITM that provides comprehensive training in AI taking into account all disciplines required for that, including aspects of CS. Other institutions also offer such undergraduate programs. For example, B.Tech in AI at IIT Hyderabad,  B.Tech in Mathematics and Computing at IIT Delhi. You can also look at the BS in Data Science and Programming at IITM, which is offered with classes in online mode with exams in in-person mode, which you can pursue alongside any other degree in any other institution.
