Like other world languages, English is used in many countries, so it has many global varieties. For example, British English differs somewhat from U.S. English in certain vocabulary (bonnet for hood of a car), syntax (to hospital rather than to the hospital), spelling (centre rather than center), and pronunciation. If you have learned a non-American variety of English, you will want to recognize, and to appreciate, the ways in which it differs from the variety widely used in U.S. academic settings.
