Is it okay to study British English books but listen only to American English?
I am learning English through the Cambridge English in Use series (grammar and vocabulary), which are British books. Is it okay if I study the British Cambridge books but listen only to American English? Or do I need to listen to British English because the books are British and the listening and studying should match?
For context, British content is very limited for me and I don’t understand the British accent at all, whereas there is a huge amount of American content and I understand the American accent easily.
Are British and American English mostly the same in terms of grammar and vocabulary, with pronunciation being the main difference?
