What's the difference between will and going to?

Use will if you decide right at the moment of speaking, like "The phone is ringing — I will get it." Use going to if the plan already existed before you spoke, like "I am going to call the bank tomorrow."

When should I use present continuous for the future?

Use present continuous for a fixed arrangement, usually with a stated time or place, such as "I am seeing the doctor at 4pm."

How do I make predictions sound natural on Speaking Task 4?

Base each prediction on a visible clue and soften it with words like probably or most likely, for example: "The sky is getting dark, so it is probably going to rain, and the people will most likely pack up their picnic."

Use will for instant decisions and general predictions, be going to for plans already decided or predictions with visible evidence, and present continuous for fixed arrangements with a time or place. On Speaking Task 4, base every prediction on a clue and soften it with words like probably or most likely, since the future is never certain.

Key strategies

1.will = instant decisions, promises, and general predictions: "I think it will rain."
2.be going to = plans already decided, or predictions based on evidence: "Those clouds mean it is going to rain."
3.Present continuous = fixed arrangements with a time/place: "I am meeting her on Friday."
4.Soften predictions with probably, most likely, I think — the future is never certain.

Three futures

will + base verb — a decision made at the moment of speaking, a promise, or a general prediction:
- "That bag looks heavy — I will carry it for you." (instant decision)
- "I think prices will rise next year." (prediction)
be going to + base verb — a plan you have already decided, or a prediction with visible evidence:
- "We are going to paint the kitchen this weekend." (plan)
- "Look at the sky — it is going to storm." (evidence)
present continuous — a fixed arrangement, usually with a time or place:
- "I am seeing the doctor at 4pm."

will vs. going to — the quick test

If the plan existed before you spoke, use going to. If you decide as you speak, use will.

"The phone is ringing — I will get it." (decided now) "I am going to call the bank tomorrow." (already planned)

CELPIP application

Speaking Task 4 (Making Predictions) is built on the future. Base each prediction on a clue and soften it:

"The sky is getting dark, so it is probably going to rain, and the people will most likely pack up their picnic."

Notice probably / most likely — predictions should sound like reasoned guesses, not certainties.
