🌟 What are “Be going to” and “Will” for?
Both forms talk about the future, but we use them in different situations:
- Be going to ➔ for decided plans and predictions based on real signs in the present 📅🔮
- Will ➔ for spontaneous decisions, offers, promises or general predictions ✋🔮
🔍 How do we form them?
Be going to:
Subject + am/is/are + going to + base verb
- I am going to study English tomorrow. ➔ (I have already decided.) 📚
Will:
Subject + will + base verb
- I will help you with your homework. ➔ (I decide now, as I speak.) 📖

❓ When do we use “Going to”?
