Options post GCSE in India

What are the options for a student moving from UK to India after the GCSE exam?
Do they have an international A levels system out there? Or perhaps the Internatiional Baccalureate, if that still exists?

Or do students go straight into Uni?

You can find an exam centre for international A levels in India. And I'm sure there are schools who teach international A levels but you just have to find one. I don't know how common IAL is in India. And obviously, India has its own education system where students study 2 years in college after SSC (Indian version of GCSE) that they call IPE or board exams (Indian version of A levels) I think.

Are there schools in India that have the IAL or IB system? How can I connect with people who have completed either of these in India?
