Which Is Easier, IELTS, TOEFL, or Duolingo? A Complete Comparison

If you need an English proficiency test for university admission, choosing between IELTS, TOEFL, and the Duolingo English Test (DET) can be confusing. All three measure English skills, but they differ significantly in test length, question style, preparation, cost, results, and acceptance.

So, which is easier: IELTS, TOEFL, or Duolingo?

For most students, Duolingo is the easiest and quickest option because the test takes about 1 hour, can be completed online from home, costs considerably less, and uses an adaptive format. IELTS is more traditional and includes separate listening, reading, writing, and speaking components. TOEFL is also comprehensive and tends to feel more academic, particularly in its reading and listening sections.

However, easier does not automatically mean better. Your university, destination country, required score, preparation time, and preferred testing environment should all influence your decision.

Which Test Is Easiest?

If your only priority is ease, speed, and convenience, the Duolingo English Test generally has the advantage.

The approximate difficulty order is:

• Duolingo English Test: Easy to Moderate
• IELTS: Moderate
• TOEFL: Moderate to High

This does not mean every student will find Duolingo easy. Your English level, familiarity with computers, typing speed, speaking ability, and ability to work under time pressure can change your experience.

IELTS may feel easier if you prefer a traditional exam with clearly separated sections and a human speaking interaction. TOEFL may suit students who are comfortable with academic English and longer reading and listening tasks.

Why Is Duolingo Usually Considered Easier?

The biggest advantage of Duolingo is its short and flexible format.

The complete test takes approximately 1 hour, compared with about 2 hours 45 minutes to 2 hours 55 minutes for IELTS and roughly 1 hour 56 minutes to 3 hours 23 minutes for TOEFL, depending on the format and source.

Duolingo also uses an adaptive test, meaning the difficulty of questions can change based on your performance. Instead of spending several hours moving through long fixed sections, you complete a shorter assessment covering reading, writing, listening, and speaking skills.

The basic structure includes:

• About 5 minutes for introduction and onboarding
• About 45 minutes for the adaptive test
• About 10 minutes for writing and speaking samples

This makes Duolingo particularly attractive to students who want a fast testing experience.

Another major advantage is availability. Duolingo can generally be taken anytime online, while IELTS and TOEFL traditionally depend more heavily on available test dates or appointments.

IELTS: Easier Than TOEFL for Some Students

IELTS may be easier for students who prefer a traditional test structure.

IELTS Academic has four main sections:

• Listening
• Reading
• Writing
• Speaking

The listening section contains 4 sections and 40 questions and takes about 30 minutes, with an additional 10 minutes sometimes provided for transferring answers in the paper format.

The reading section contains 40 questions and lasts 60 minutes.

The writing section includes 2 tasks and takes 60 minutes.

The speaking test normally takes around 11–14 minutes.

The entire IELTS test takes approximately 2 hours 45 minutes to 2 hours 55 minutes, depending on the format and timing of the speaking component.

For students who prefer speaking directly with an examiner, IELTS can actually feel more comfortable than an entirely computer-based assessment.

However, the longer writing and reading sections mean that IELTS generally requires more preparation than Duolingo.

TOEFL Can Feel More Difficult

Among the three, TOEFL is often viewed as the most academically demanding, particularly by students who struggle with long reading passages, lectures, or integrated academic tasks.

TOEFL includes four major skills:

• Reading
• Listening
• Speaking
• Writing

The older or source-specific structure cited by comparison articles includes 3–5 reading passages with 36–74 questions, 6–9 listening lectures with 28–39 questions, 4 speaking tasks, and 2 writing tasks.

The more recent TOEFL format is shorter than some older descriptions, so students should always check the current official test structure before booking.

What makes TOEFL challenging is not simply the number of sections. The test places considerable emphasis on academic English, which can require stronger comprehension and concentration.

If you are comfortable reading academic material, listening to lectures, taking notes, and responding quickly, TOEFL may not feel especially difficult. For other students, it can require considerably more preparation.

IELTS vs TOEFL vs Duolingo: Test Length

Test duration is one of the clearest differences.

Duolingo takes about 1 hour, making it the shortest of the three.

IELTS takes around 2 hours 45 minutes to 2 hours 55 minutes, including its four skill areas.

TOEFL can take around 2 hours in its newer format, while older comparisons and formats have listed approximately 2 hours 47 minutes to 3 hours 23 minutes.

For students who become tired during long examinations, Duolingo’s shorter format can be a major advantage.

A shorter test does not necessarily mean less preparation, though. You still need sufficient English proficiency to achieve your target score.

Which Test Is Cheapest?

If budget is important, Duolingo is usually the least expensive option.

The competitor comparisons list Duolingo at around $49, while another comparison gives a current range of approximately $59–$69 depending on location and pricing.

IELTS is commonly listed around $215–$250, although prices vary by country and test center.

TOEFL is listed around $200–$235 in the competitor material, again depending on location, taxes, and registration conditions.

For example, one comparison lists:

• Duolingo: $49
• IELTS: $215–$250
• TOEFL: around $235

Two Duolingo tests were also listed at approximately $118 in one competitor comparison.

Because test fees can change by country and date, students should confirm the final price before registration.

Which Test Gives Results Faster?

If you need your result quickly, Duolingo has a significant advantage.

Duolingo results are generally reported within 48 hours, or about 2 days.

IELTS results can take around 13 days in the comparison material, although delivery time can vary according to test format.

TOEFL results depend on the current testing and reporting system, with competitor information ranging from several days to around 4–8 days.

This makes Duolingo particularly useful for students dealing with a tight application deadline.

Can You Book Duolingo at the Last Minute?

This is another area where Duolingo stands out.

Duolingo is available 24/7 online, allowing students to register and take the test without waiting for a traditional test-center date.

The comparison material shows that IELTS online appointments are available with around 48 hours’ notice, while TOEFL may require approximately 2–3 weeks’ advance planning, depending on availability.

TOEFL Home Edition information in one competitor source also lists availability 24 hours a day, 4 days a week, with appointments potentially available as early as 24 hours after registration.

Therefore, if your deadline is approaching quickly, Duolingo can offer much more flexibility.

Which Test Is More Widely Accepted?

This is where the decision becomes more complicated.

IELTS and TOEFL have much broader global recognition than Duolingo.

The competitor data lists IELTS as being accepted in 140+ countries and by more than 11,000–12,000 organizations or institutions, depending on the source.

TOEFL is described as being accepted in 150+ countries and by approximately 11,000–12,500 institutions.

Duolingo is also widely accepted, with competitor sources citing approximately 3,000–5,000+ institutions, including a figure of 4,603 schools in one comparison.

Therefore, you should never choose Duolingo simply because it is easier.

First, check whether your exact university and program accept DET.

Does Your University Accept Duolingo?

University acceptance can completely change which test is the best choice.

For example, competitor research includes Duolingo requirements such as:

University College London: IELTS 6.5, Duolingo 135

University of South Alabama: IELTS 6.5, Duolingo 105

Northern Arizona University: IELTS 6.5, Duolingo 115

Southern Alberta Institute of Technology: IELTS 5.5, Duolingo 110+

NorQuest College: IELTS 5.5, Duolingo 100+

Trinity Western University: IELTS 6+, Duolingo 115+

Thompson Rivers University: IELTS 6.5+, Duolingo 110+

Yorkville University: IELTS 6+, Duolingo 120+

Dalhousie University: IELTS 6.5+, Duolingo 115+

Vancouver Community College: IELTS 6+, Duolingo 105+

These examples show why there is no universal passing score.

A 120 Duolingo score might be enough for one institution but insufficient for another.

Always check the exact admission requirements for your program.

IELTS, TOEFL, and Duolingo Score Ranges

The scoring systems are completely different.

IELTS uses a 0–9 band scale.

TOEFL iBT traditionally uses a 0–120 scale, although the test’s scoring system has been updated, so students should check the current official score reporting format.

Duolingo uses a 10–160 scale.

A commonly cited IELTS-to-Duolingo comparison is:

• IELTS 8.5–9 ≈ Duolingo 160
• IELTS 8 ≈ Duolingo 150–155
• IELTS 7.5 ≈ Duolingo 140–145
• IELTS 7 ≈ Duolingo 130–135
• IELTS 6.5 ≈ Duolingo 120–125
• IELTS 6 ≈ Duolingo 105–115
• IELTS 5.5 ≈ Duolingo 95–100
• IELTS 5 ≈ Duolingo 80–90
• IELTS 4.5 ≈ Duolingo 65–75
• IELTS 0–4 ≈ Duolingo 10–60

These conversions should be treated as approximate comparisons, not universal admission equivalents. Universities set their own minimum requirements.

Which Test Requires More Preparation?

Preparation depends heavily on your existing English level.

For many students, Duolingo requires less preparation time because the exam is shorter and its format is relatively compact.

IELTS usually requires preparation across four separate skills, with particular attention to writing structure and speaking performance.

TOEFL can require additional preparation for academic reading, listening, integrated speaking, and writing.

A student with strong academic English might prepare quickly for TOEFL, while someone who is comfortable speaking face-to-face could prefer IELTS.

The most important factor is not simply how difficult the exam looks. It is how well the test format matches your strengths.

A Simple 15-Day Duolingo or IELTS Preparation Approach

If you have only around two weeks, a focused schedule can help.

Days 1–2: Learn the Test Format

Understand every section, question type, timing rule, scoring area, and technical requirement.

Do not begin by taking endless practice tests. First understand what the test expects.

Days 3–6: Focus on Weak Skills

Spend these days working on reading, listening, vocabulary, grammar, and integrated tasks.

Identify your weakest areas rather than spending equal time on everything.

Days 7–10: Practice Writing and Speaking

Work on short, timed responses.

For IELTS, pay particular attention to writing tasks and speaking responses.

For Duolingo, practice producing clear answers quickly because the test is highly time-sensitive.

Days 11–12: Take Full Practice Tests

Complete realistic practice tests under timed conditions.

Record your mistakes and identify patterns.

Days 13–15: Review and Relax

Review your weak areas, revise common mistakes, and avoid excessive last-minute studying.

Getting enough sleep and entering the test with a clear mind can be more useful than trying to learn large amounts of new material at the last moment.

Which Test Is Better for Studying in the USA?

For the United States, TOEFL, IELTS, and Duolingo can all be useful, but acceptance varies by institution and program.

The competitor research mentions universities such as Harvard, MIT, Stanford, Northeastern, NYU, and Colorado State in destination-based comparisons.

Some highly competitive universities may have demanding English-language requirements. One comparison mentions an Ivy League TOEFL requirement of 100 and IELTS requirements around 7.0–8.0.

Do not assume that a university accepts every test simply because another university does.

Check the admission page for your exact program before paying for an exam.

Which Test Is Better for the UK?

IELTS has historically been a very familiar choice for UK study applications, but other tests may also be accepted depending on the institution.

The competitor research mentions UK institutions including:

• Oxford
• Cambridge
• University College London
• Coventry University
• Queen Mary University of London
• University of Stirling

Duolingo and PTE may be accepted by some institutions, but requirements can differ by university, course, and visa situation.

If you are applying to the UK, verify the exact English-language requirement before selecting your test.

Which Test Is Better for Canada?

Canada is another destination where acceptance can vary between institutions and programs.

The competitor research mentions institutions including:

• University of Toronto
• University of British Columbia
• McGill University
• Toronto Metropolitan University
• University of Calgary
• McMaster University

IELTS remains a widely recognized option, while TOEFL and Duolingo may also be accepted by many institutions.

If your university accepts all three and you need the fastest, cheapest option, Duolingo may be worth considering.

IELTS, TOEFL, or Duolingo for Australia?

For Australia, IELTS is traditionally one of the most recognized English tests, while TOEFL and PTE are also used by many institutions.

The competitor comparison specifically identifies IELTS, PTE, and TOEFL as major Australian options.

Duolingo acceptance can be more limited depending on the institution and purpose.

If Australia is your destination, don’t choose based on test difficulty alone. University acceptance should come first.

Can You Take All Three Tests at Home?

The home-testing experience differs significantly.

The Duolingo English Test is designed to be taken online from home and is available anytime.

The TOEFL iBT Home Edition is also a home-based option. Competitor information lists it as available 24 hours a day, 4 days per week, with appointments potentially available 24 hours after registration.

An IELTS home-based option mentioned in the competitor material is IELTS Indicator, which was listed at $149, took approximately 2 hours 45 minutes, used a 0–9 score scale, and provided results within 7 days.

However, availability and acceptance of specific home-testing versions can change. Always verify the current version available in your country and whether your institution accepts it.

Which Test Should You Choose?

The easiest way to decide is to start with your university requirement, not the exam itself.

Choose Duolingo if you want a short, affordable, flexible online test and your university accepts it. It is especially attractive when you need results quickly.

Choose IELTS if you prefer a traditional four-section exam, want a human speaking interaction, or need a test with very broad international recognition.

Choose TOEFL if you are comfortable with academic English, computer-based testing, reading passages, lectures, and integrated tasks, particularly when your target institution strongly recognizes TOEFL.

Final Verdict

For pure ease and convenience, Duolingo generally comes out ahead.

It takes about 1 hour, costs far less than the approximately $200+ commonly listed for IELTS and TOEFL, can be taken online, and usually delivers results within about 48 hours.

IELTS is more detailed and takes around 2 hours 45 minutes to 2 hours 55 minutes, while TOEFL can be academically demanding and may require more preparation for students who are less comfortable with academic English.

But the best test is not necessarily the easiest test.

Before registering, check three things: your university’s accepted tests, your required score, and your application deadline. If Duolingo meets all three, it can be the fastest and most convenient choice. If not, IELTS or TOEFL may be the safer option despite requiring more time and preparation.
