English is not the same in all places of our planet. People use English in America, Australia, Canada and Great Britain as their mother tongue, but these "English" are different. We can talk about American English, Australian English, Canadian English. People living in the UK speak English. Those who live in India speak Indian English. British English and American English are the most important types of English, because people use them very widely. But they are not really that different. You are learning British English, but if you meet people who come from the United States, you can understand what they are saying. You may not understand everything, you may find that some words do not sound very ordinary. Of course, you can say that these people are not British, but you can still talk to them. This is because the vocabulary and grammar of the language is very much the same. But some things have different names in the UK and America.
