CELPIP Grammar Practice — Prepositions & Fill-in-the-Blank
Prepositions (in, on, at, for, to…) are a common source of small errors that add up across CELPIP Writing and Speaking. The Complete it game gives you AI-generated sentences with one word missing so you can build accuracy fast.
How this task works
This isn't a separate section of the CELPIP test — it's targeted practice for the grammar and word choice that raters notice everywhere. Each round gives a natural sentence with a gap; you choose or type the word that fits.

A worked example
Here's a real example of the kind of task and answer you'll practise. On the app, the content is generated fresh each round.
I've been living ___ Toronto since 2019.
- A. at
- B. in ✓
- C. on
- D. to
Why: Use 'in' for cities and countries: in Toronto, in Canada. 'at' is for specific points/addresses.
She's really good ___ solving problems under pressure.
- A. at ✓
- B. in
- C. for
- D. with
Why: The collocation is 'good at + activity': good at solving, good at math.
Please send the report ___ me by Friday.
- A. at
- B. for
- C. to ✓
- D. on
Why: You send something 'to' a person. 'for' would change the meaning to 'on my behalf'.
Tips to score higher
- ✓Learn prepositions inside phrases (good at, depend on, interested in), not in isolation.
- ✓When you read English, notice the preposition that follows common verbs and adjectives.
- ✓Keep a short list of pairs you get wrong and review it before the test.
- ✓In Writing, a wrong preposition rarely blocks meaning but does lower your accuracy score.
