No time?

Hi, I am a 17-year-old student currently in Grade 12, living in India. I am studying Cambridge International A Levels with the following subjects: Physics, Chemistry, Biology, Pure Mathematics, and Statistics.

At the moment, I feel quite uncertain about my future. Firstly, I am unsure about the best subject combination to pursue further. Secondly, I do not know how to choose suitable colleges or universities.

Personally, I prefer Pure Mathematics and Biology over Physics and Chemistry, so I am somewhat inclined toward the field of Biotechnology. However, I also want to choose a major that is less likely to be replaced or significantly affected by AI in the future.

Additionally, I am unsure whether I should take S2 (Statistics 2) or M1 (Mechanics 1) as my second mathematics component.

Any guidance or advice would be greatly appreciated.
