Choosing between IELTS, TOEFL, PTE, and Duolingo can feel overwhelming when you're planning to study abroad. Each test has different formats, costs, and acceptance rates across universities worldwide. The wrong choice could mean wasted money, delayed applications, or even visa rejection.
If you're asking yourself "which English test should I take" for your international education goals, this comprehensive comparison will help you make an informed decision based on your destination country, budget, and personal strengths.
Understanding the Four Major English Proficiency Tests
Before diving into comparisons, let's understand what each test offers:
IELTS (International English Language Testing System) is the most widely recognized English proficiency test globally, accepted by over 11,000 institutions worldwide. Jointly managed by the British Council, IDP, and Cambridge English, IELTS assesses Listening, Reading, Writing, and Speaking skills through both paper-based and computer-based formats. Learn more about IELTS on the official website. The Academic version is designed for university admissions, while General Training serves immigration and work visa purposes.
TOEFL (Test of English as a Foreign Language), created by ETS, focuses heavily on academic English and is preferred by American universities. The iBT (internet-based test) format lasts approximately 2 hours and evaluates Reading, Listening, Speaking, and Writing through integrated tasks that mirror real academic situations. Visit the official TOEFL website for complete test information.
PTE (Pearson Test of English) Academic uses AI-powered scoring for completely computer-based testing. Known for its quick results—typically within 1-2 days—PTE has gained popularity among students applying to UK and Australian institutions, particularly for immigration purposes. Check PTE Academic's official page for test details.
Duolingo English Test (DET) emerged as the most affordable and flexible option, especially after 2020. Taken entirely from home with results in 48 hours, this adaptive test costs significantly less than traditional options. Visit Duolingo English Test to learn more. However, its acceptance remains more limited compared to the established trio.
Cost Comparison: Which is the Cheapest English Language Test?
Budget plays a crucial role when choosing your English proficiency test. Here's how the four tests compare:
IELTS costs approximately ₹17,000-₹18,500 in India, varying slightly by test center and format (paper vs computer-based).
TOEFL iBT costs around $190-$250 (approximately ₹15,800-₹20,800), with pricing dependent on your country and test location.
PTE Academic ranges from ₹15,000-₹18,500 in India, with prices varying based on test center and scheduling.
Duolingo English Test stands out as the most budget-friendly option at just $65 (approximately ₹5,400), making it dramatically cheaper—nearly 70% less expensive than traditional tests.
For students on tight budgets, Duolingo offers unmatched affordability. However, remember that choosing the cheapest English language test only makes sense if your target universities accept it.
Test Format and Duration: Finding Your Comfort Zone
Understanding test formats helps you choose based on your strengths and preferences.
IELTS lasts approximately 2 hours 45 minutes total. The Speaking test can be scheduled separately and involves face-to-face interaction with a certified examiner—ideal for students who perform better in conversational settings rather than speaking to a microphone. Explore KD Global Edu's IELTS preparation program for structured guidance.
TOEFL completes in about 2 hours with all sections computer-based. Speaking responses are recorded rather than delivered to a person, which some students find less intimidating while others miss the human interaction. Our TOEFL preparation courses help you master this format.
PTE finishes in roughly 2 hours with fully automated, computer-based testing. Integrated tasks require typing speed and comfort with technology. The AI scoring eliminates potential examiner bias but demands precise pronunciation and clear speech patterns.
Duolingo takes just 1 hour—the shortest among all options. Its adaptive format adjusts question difficulty in real-time based on your performance. The test includes a 45-minute graded section plus unscored video interview and writing samples sent to institutions.
For time-conscious students or those uncomfortable with lengthy exams, Duolingo and TOEFL offer quicker completion times.
Global Acceptance: Best English Test for Different Countries
Where you plan to study significantly influences which English test should I take:
For USA universities, TOEFL remains the gold standard with widest acceptance, though most also accept IELTS and PTE. Duolingo test acceptance has grown substantially, with over 4,000 American institutions now recognizing it. Check Duolingo's university acceptance list for specifics.
For UK institutions, IELTS historically dominated, but PTE has gained strong acceptance. Some visa categories specifically require IELTS for UKVI (UK Visas and Immigration). Duolingo acceptance is growing but requires verification with specific universities.
For Canada, both IELTS and TOEFL enjoy equal acceptance for university admissions. With the recent discontinuation of the Student Direct Stream (SDS) program, students now have more flexibility to choose home-based options like Duolingo.
For Australia, IELTS and PTE lead for both university admissions and immigration purposes. PTE particularly excels for Australian PR applications due to its quick results and AI scoring. Duolingo acceptance is limited for Australian student visas.
For European countries, IELTS and PTE see broader acceptance across institutions, though specific university requirements vary considerably.
Always verify your target university's accepted tests before booking any exam—this single step prevents costly mistakes.
Scoring Systems and Result Timeline
Each test uses different scoring scales and delivers results at varying speeds:
IELTS scores range from 1-9 bands with 0.5 increments. Results arrive in 13 days for paper-based tests and 3-5 days for computer-based versions. Most universities require band 6.5-7.0 for undergraduate programs and 7.0-7.5 for competitive postgraduate courses.
TOEFL scores span 0-120 total points. Results appear within 6-10 days of test completion. Typical university requirements fall between 79-100, with top-tier institutions demanding 100+.
PTE scores use a 10-90 scale with the fastest result delivery—typically 1-2 business days. Universities generally require 58-75 for admission, making PTE particularly attractive for students with tight application deadlines.
Duolingo scores range from 10-160 with results delivered within 48 hours—the absolute fastest turnaround. Most universities accept scores between 110-130, roughly equivalent to IELTS 6.5-7.0.
For urgent applications or visa deadlines, PTE and Duolingo offer significant advantages with their rapid result delivery.
Difficulty Level: Which English Test is Easier for Students?
"Which test is easier" depends entirely on your individual strengths and learning style.
IELTS suits students who:
- Excel in face-to-face conversations
- Prefer traditional pen-and-paper writing

- Perform well under structured, predictable formats
TOEFL works best for students who:
- Are comfortable with American English and academic contexts
- Can sustain concentration for integrated listening-speaking-writing tasks

According to test-taker feedback across forums, PTE and Duolingo often feel "easier" to score well on due to AI scoring patterns and shorter duration, while IELTS vs TOEFL require more consistent preparation across longer test formats.
Preparation Requirements: How Much Study Time Do You Need?
For IELTS, timing depends on your starting level and chosen learning format:
Batch classes
- 8-12 weeks of structured preparation to move from an intermediate level to band 7.0+.
1-on-1 model
- With KD Global Edu's personalized 12-hour program, completion time is flexible—6 weeks with 2 classes per week, or 4 weeks with 3 classes per week, depending on your schedule and intensity preference.
For TOEFL, expect similar flexibility:
Batch classes
- 6-10 weeks of dedicated study, focusing heavily on academic vocabulary and integrated task practice.
1-on-1 model
- 4-6 weeks with personalized instruction, adjusting pace based on your starting level and target score.
For PTE, the test's predictable patterns allow for faster preparation:
Batch classes
- 4-8 weeks with scoring templates and pattern recognition strategies.
1-on-1 model
- 3-6 weeks with focused, individualized practice on weak areas.
For Duolingo, given its shorter format:
Batch classes
- 2-6 weeks of focused practice typically prepares students adequately.
1-on-1 model
- 2-4 weeks with intensive, personalized preparation.
At KD Global Edu, our preparation programs offer both batch and 1-on-1 personalized instruction. The 1-on-1 model provides maximum flexibility—our standard 12-hour intensive program can be completed in just 6 weeks (2 sessions weekly) or even 4 weeks (3 sessions weekly) based on your availability and learning pace. We emphasize diagnostic assessments to identify your starting level and create personalized strategies to achieve target scores efficiently.
The actual timeline depends on where you start—students with intermediate proficiency progress faster than absolute beginners. Most students see noticeable improvement within 4-8 weeks of consistent participation in our live online classes with recorded sessions for review.

Frequently Asked Questions (FAQs)
Can I take multiple English tests and submit my best score?
Yes, you can take different tests and submit whichever score is highest, as long as your university accepts multiple test types. However, this approach becomes expensive quickly. We recommend choosing one test, preparing thoroughly, and taking it once or twice rather than spreading effort across multiple formats.
Do universities prefer one test over others?
Most universities accept multiple tests without preference, but US institutions historically favor TOEFL while UK/Australian universities lean toward IELTS and PTE. Always check specific university requirements—some graduate programs or scholarships may specify particular tests.
How long are test scores valid?
IELTS, TOEFL, and PTE scores remain valid for 2 years from the test date. Duolingo scores are also valid for 2 years. Plan your test timing so scores remain valid throughout your entire application and visa process.
Can I retake the test if I'm unhappy with my score?
All four tests allow unlimited retakes, but you must wait minimum periods between attempts: IELTS and PTE require no waiting period, TOEFL requires 3 days between tests, and Duolingo requires 24 hours. However, multiple attempts become expensive except for Duolingo.
Is Duolingo really accepted by top universities?
Which test is best for non-native English speakers with limited practice?
For beginners or students with limited English practice, PTE and Duolingo often feel more manageable due to their adaptive nature and AI scoring patterns that follow predictable templates. However, with proper preparation through programs like those at KD Global Edu, students at any level can achieve competitive scores on any test.
Do English proficiency test scores affect scholarship opportunities?
Yes, higher test scores can significantly impact scholarship eligibility. Many merit-based scholarships have minimum score requirements (often IELTS 7.0+ or TOEFL 100+). Exceptional scores can also strengthen your overall application competitiveness even when not explicitly required for scholarships.
