What are suitable UG and PG educational paths for my mathematically inclined daughter, currently in 6th standard, that could lead to a successful career?

It is a bit early to gauge your daughter's interests, but we recommend that she keep up with the current science and technology news to see what piques her interest. Based on her interests, later on, she can choose engineering or pursue a career in the sciences. Many students with a forte in maths also decide to become accountants or pursue finance.
