Where it appears in the exam
What is it?
The future in English is expressed with three competing forms: WILL (spontaneous decision, opinion-based prediction, promises), GOING TO (pre-existing plan, evidence-based prediction) and PRESENT CONTINUOUS (fixed arrangement with time/place). Additionally, time clauses (when, if, as soon as) demand Present Simple — never will. Most languages handle future with one or two forms, without the plan vs fixed arrangement distinction.
Why it matters in the exam
It's the most exploited future competency in B2 First. Part 2 (Open Cloze) tests it with high intensity: you must produce will, going, am or the verb in present tense with no options. The time clause trap is lethal because most languages use future or subjunctive forms where English demands present simple.
The cognitive trap
"Your brain picks the simplest future form and uses it for everything"
This is cognitive economy: your brain has one category for 'things that will happen' and doesn't naturally split it into spontaneous vs planned vs arranged. The distinction feels artificial because in your mental model, a future event is just a future event — the circumstances of how you decided don't seem grammatically relevant.
"I'm seeing the doctor tomorrow" ≠ "I'm going to see a doctor" ≠ "I'll call you when I arrive"
3 forms with distinct rules. Fixed arrangement = present continuous. Plan/intention = going to. And in time clauses: NEVER will — always Present Simple.
Recognition pattern
In the exam, look for the key signal first. The answer follows.
Signals that determine the future form
"I'll call you when I get home."
"I think she will pass the exam."
"Look at those clouds — it's going to rain."
"The phone's ringing. I'll answer it."
"I'm going to learn French next year."
"I'm having lunch with Sarah at 1pm."
"I promise I won't tell anyone."
"Shall I open the window?"
"I've decided — I'm going to quit my job."
"We're flying to Rome on Saturday."
The 4 errors that Cambridge exploits
"I'll call you when I will arrive."
The #1 error across all language backgrounds. The rule is absolute: NEVER will after when/if/as soon as.
"I'll call you when I arrive."
Time clause (when) → Present Simple in the subordinate clause. Will only in the main clause.
"Look at those clouds — it will rain."
Will = opinion ('I think it will rain'). With visible evidence RIGHT NOW, Cambridge demands going to.
"Look at those clouds — it's going to rain."
Visible evidence (clouds) → going to. The prediction is based on what you CAN SEE, not on opinion.
"I'm going to meet Sarah at 6pm tomorrow."
Going to sounds like an intention. With concrete logistical details (person + time), Cambridge expects present continuous.
"I'm meeting Sarah at 6pm tomorrow."
Fixed arrangement: person (Sarah) + time (6pm) + day (tomorrow) = present continuous.
"Don't worry, I'm going to carry your bag."
Going to implies you had already decided before. But you just saw the person needs help — it's spontaneous.
"Don't worry, I'll carry your bag."
Spontaneous offer — you decide NOW, in response to the situation. Will.
Why your brain gets it wrong
The learner's short circuit
Analyse the trap by exam format
I will send you the information as soon as I ______ back to my desk.
Your brain translates a future concept and produces 'will get'. But in English, 'as soon as' DEMANDS Present Simple. Will is impossible here.
as soon as
'as soon as' = time clause → Present Simple. The main clause already has will — the subordinate NEVER repeats will.
→ get
The most lethal trap across all language backgrounds
Most languages use a future or subjunctive form in time clauses. In English, the rule is absolute: when/if/as soon as/until/before/after + Present Simple.
Strategy
Locate the time clause FIRST. If there's when/if/as soon as/until/before/after, write the verb in present tense. The main clause takes will — the subordinate NEVER does.
Be careful! That shelf is overloaded — it looks like it ______ going to collapse.
Your brain sees 'future' and writes 'will'. But 'it looks like' + visible situation = evidence-based prediction. That demands going to. The gap asks for 'is' (the auxiliary of 'is going to collapse').
looks like
'it looks like' + visible evidence (shelf overloaded) = going to, not will.
→ is
Visible evidence = going to, ALWAYS
Cambridge designs contexts with physical evidence: clouds, broken shelves, cars with no brakes. If you CAN SEE the cause, the prediction is going to.
Strategy
Is there something visible/tangible causing the prediction? (looks like, be careful, watch out) → going to. Is it an opinion without evidence? (I think, probably) → will.
"That bag looks heavy." "Oh, thanks — I 2 help you carry it." (spontaneous reaction)
Your brain produces 'going to' as a general-purpose future. But the decision is spontaneous (you just noticed the bag). Will ('ll) marks decisions made in the moment. Going to implies you had already planned it.
When did you decide? That's the key question
Cambridge exploits the difference between 'I decide NOW' (will) and 'I had already decided' (going to). Most learners default to going to for everything.
Strategy
Ask yourself: did the person decide BEFORE speaking or AT THIS MOMENT? Reaction to a stimulus = will. Prior plan = going to.
