IELTS vs Duolingo: Which Should You Take?

IELTS vs Duolingo at a glance

Cost, results & validity

The Duolingo English Test (around US$65, about 1 hour, taken at home) is far cheaper and faster than IELTS (around US$200+, about 2h 45m, at a test centre). But IELTS is accepted for visas and permanent residence and by virtually every university — confirm Duolingo is accepted before relying on it.

Prices vary by country and change over time — always confirm the current fee and accepted test on the official test and university websites.

How to actually decide between IELTS and Duolingo

"Which is easier" is the wrong first question, and it is the one almost everyone asks. Neither test is easier in general; they are easier for different people, and the difference between them for you is usually smaller than the difference between preparing properly and not. Work through these in order instead.

1. Start with acceptance, because it can end the decision immediately. List every institution, visa route or registration body you might apply to, then check which tests each accepts — and which version. If only one test clears all of them, you are finished; the rest of this page is interesting rather than useful. This is the step people skip, and skipping it is how someone sits the wrong test and pays twice.
2. Then check the deadline against the results timeline. Turnaround differs between these two, and so does test-centre availability near popular deadlines. Work backwards from the date a score must be received — not sent — and leave room for one resit. If the calendar only permits the faster test, again, decision made.
3. Only now compare format against your own weaknesses. This is where the table above earns its place, and the comparison worth making is section by section, not test by test. A candidate who freezes with a live examiner and one who cannot keep a train of thought speaking into a microphone should choose differently, and neither is a general fact about the tests.
4. Sit a full timed mock of each before you pay. This is the only step that produces evidence rather than opinion, and it is free. Two complete papers cost you an afternoon and can save a test fee — sit them under real timing, because the difficulty that matters is the one that appears when you are tired and behind the clock.

You can do step four here, in full, today:

• IELTS: 181 free practice tests, 3,850 questions across Reading, Listening, Writing, Speaking — take a full timed mock →
• Duolingo: 150 free practice tests, 1,740 questions across Adaptive, Comprehension, Literacy, Conversation, Production — take a full timed mock →

Both counts are read from the test files this site ships rather than estimated, and every question is checked before release so its answer key matches an option you can actually select.

One caution about switching late. If you have already prepared substantially for one test, changing to the other resets the format-specific work — the timing habits, the task patterns, the marking criteria — even though your English is unchanged. That is often a bigger cost than the score difference you were chasing. Switch when acceptance or the calendar forces it; be much slower to switch because the other test looks marginally easier.

Fees, turnaround times and acceptance change, sometimes mid-year. Confirm the current position on the official test websites and with each institution before booking — the figures here are for comparison.
