Q: Is IISER better than IIT?

IISERs and IITs are both excellent institutions, but they have different focuses:

IISERs:
Primarily focus on fundamental Science research. It also offers a strong foundation in basic sciences like physics, chemistry, biology, and mathematics. This will encourage research-oriented learning from the beginning. But candidates may have fewer career options outside of academia compared to IITs.

IITs:
Primarily focus on engineering and technology. The organisation has a wide range of engineering and Science programmes. Also have a strong emphasis on practical applications and industry collaborations. Generally have more diverse career options, including in industry and research.

Which is "better" depends entirely on your individual goals and interests.

If you are passionate about fundamental Science research and want a strong foundation in basic sciences, IISERs might be a better fit. And if you are interested in engineering, technology, or have broader career aspirations, IITs might be a better choice.
