Train the Brain:

To speak proper and fluent English, train the brain to think and create sentences in English.

Being surrounded by English helps the brain become familiar with English sentences and phrases. The more familiar a language is, it becomes easy to think and speak in it.

Thus, the speaker can easily move from "I am correct No ?" to "Am I correct ?" .
