What is Caltech?

Caltech is a world-renowned science and engineering institute that marshals some of the world's brightest minds and most innovative tools to address fundamental scientific questions and pressing societal challenges.

Located in Pasadena, California, it manages NASA's Jet Propulsion Laboratory (JPL).

For Indian students, it is often compared to the IITs but with a significantly higher focus on research rather than just engineering placements. It has a very small student body (approx. 240 students per batch), making it more exclusive than MIT or Harvard.
