I am student of class 11.I want to be a botanist what I have to do after 12
Hey Yogesh.
To become a botanist you would require to have science subjects- Physics, Chemistry, Biology in your 12th. After that you should seek admission in the course of Bsc Botony in any good University/ college. Masters in Botony( Msc Botony) is also available as a course in various good Universities. You can also pursue PHD in it futher if you wish to.
Best of luck!
