Both “Will” and “Be Going to” are used to express future tense in English but they do not have the same meaning.
This lesson provides an explanation of the key differences that will help you use “be going to” and “will” correctly.
“Will” expresses a desire or agreement to do something… or a sudden decision.
- I will help you with your homework.
- I will take your temperature.
“Be going to” is used when you already have plan to do something.
