Goal
You’ll be able to talk about future plans and predictions using the correct structure for each specific situation, distinguishing genuine planned arrangements from spontaneous decisions and general predictions.
Learn
English has multiple ways to talk about the future, and choosing the right one depends on the actual situation:
I'm going to visit my family this weekend. (a plan, already decided) I'll help you with that. (a spontaneous decision, made right now) It will probably rain tomorrow. (a prediction, based on general belief) I'm meeting my friend at 6pm. (present continuous, a fixed, scheduled arrangement)
The genuinely useful distinction: going to signals a plan already decided before speaking; will signals a decision made at the exact moment of speaking, or a general prediction; present continuous signals a fixed, specific arrangement, often with a set time (like a scheduled meeting).
A realistic example showing the difference: if someone says The phone is ringing, and you spontaneously respond I’ll get it! — this spontaneous decision genuinely requires will, not I’m going to get it, since the decision was made at that exact moment, not planned beforehand.
Decision Task
The phone starts ringing, and you spontaneously decide, right at that moment, to answer it. Before reading on: would you say I’m going to get it or I’ll get it?
Show Answer
I’ll get it! — since this is a spontaneous decision made at the exact moment of speaking (not a plan decided beforehand), will is the correct choice. I’m going to get it would incorrectly suggest this was already planned before the phone started ringing.
Common Mistake
Using going to for a spontaneous decision made at the moment of speaking, rather than reserving it for plans genuinely decided beforehand. The distinction between “already decided” (going to) and “deciding right now” (will) is a real, meaningful one, not just a stylistic choice.

I’m going to visit — since this was already decided/planned beforehand.
2. Write a general weather prediction using “will”.

Any correct example, e.g. It will probably be sunny tomorrow.
3. Write a sentence describing a fixed, scheduled arrangement using present continuous.
Show Answer
Any correct example, e.g. I’m meeting my friend at 6pm.
4. What does “going to” signal about a future action?

A plan already decided before the moment of speaking.
5. What does “will” signal when used for a spontaneous decision?

Try It Yourself
Without looking back, write two sentences: one describing a future plan you decided earlier (using “going to”), and one describing a spontaneous decision you’re making right now (using “will”).
Show Answer
For example: I’m going to study tonight. (I decided this earlier.) Someone just asked for help — I’ll help them now. (a spontaneous decision.)
