Need help with choosing what to do for Life sciences as an 11th grader in india.

I am from India, so if any Indians in this sub could help me out, it would be greatly appreciated.

Myquals: Im a passed 10th grader, got 80.2% in my boards, and want to pursue Marine bio/Life sciences.

I know I'll have to choose PCB in class 11th, however I need to know which board is better for class 11th, CBSE or state board(Maharashtra).

I do wish to travel abroad later for my career as I do not think the options of research fields like marine biology and zoology are valued here much.

If anyone could guide me in what my path should look like it would be appreciated.
