CAPITALISATION

Capitals are used at the beginning of a sentence, for proper nouns, for the titles of officers, works, books, films, etc.: the President of India, Parliament, the Prime Minister Narendra Modi the Vice-Chancellor Arun Desai, 'Sound of Music', Twelfth Night, Padma Bhushan, Nobel Prize.

We should not use capital when you are talking of the generic: for example, 'The prime minister of the country have done their best to improve the economy.' Or 'You need to think of which subject you would like to take up: chemistry, physics and biology are much prepared, but the humanities is not any the less important.'
