Question

what subject should taken in 11 std to become psychologist​

Answer 1

You will also be required to take several biology classes, chemistry, statistics and other mathematic classes. During this part of your education you should have a general idea of the field of psychology you are interested in, in order to work towards either a bachelor of arts degree or a bachelor of science degree.

Answer 2

Psychology?

And maybe back it up with some subjects you really like.

And I'd say maths is a bit on the down side and it's optional because if you take it, it's time consuming and I prefer you don't take it if you're not much in favour of time and it's limitations. But take it if you can do it. Because no one's stopping you from greatness! Good luck!
