Conditional Sentences Exercises With Answers (All Types, PDF)

The hard part of conditionals isn't the form — it's choosing the right one for the meaning. Students who can fill a first-conditional gap perfectly will still say 'If I would have time' because the jump into unreal situations (second and third) doesn't match how their first language works.

So before downloading a worksheet, decide which types you're practising. A set that mixes all four is useful for review but overwhelming as first practice. Early on, a PDF that isolates one type — or contrasts just two (first vs second) — produces clearer learning than a grand mixed test.

These sites offer printable conditionals practice with keys, sorted by type and level:

Read the answer key first. Conditionals often allow more than one natural answer ('if it rains' vs 'if it's raining'; 'would' vs 'could'/'might' in the result clause), so confirm the key matches what you teach and flag items where you'll accept alternatives.

Then check the level and the mix. A B1 class needs first and second conditionals with a small amount of contrast; a full four-type mixed set is better saved for B2 review.

Finally, count the items. A 30-item mixed conditionals test can take B1 students 30–40 minutes — fine as a review, too long as a warm-up. For a quick check, 8–10 well-chosen items are enough.

A worksheet gives students the answers but doesn't show you where the meaning broke down. If you want that, take a handful of sentences from your own lesson — the exact contrasts you taught — and run them as a short end-of-lesson quiz.

Because the questions come from what you covered, the results are specific: if half the class chooses a first-conditional form where the meaning is clearly unreal, you know to spend five minutes on second-conditional meaning next lesson rather than reteaching the whole topic.
