🧠 The Smartest Way to Take the Duolingo English Test (And Save Time + Money)

If you're preparing to take the Duolingo English Test (DET), you're likely making some big decisions about your future. Maybe you're applying to a university in the U.S., working toward a scholarship, or trying to meet the language requirements for a visa.

And in the middle of all that planning, you're asked to pay $70 for a test — maybe more if you're on a tight timeline.
Now you're asking yourself: Is this really the best way to spend my money?

This article is for students who want clarity. It’s a logical, step-by-step guide to saving money and reducing stress — without cutting corners — by using an official DET coupon code from a source you can trust: DET Study.

📚 First, What Is the DET — and Why Are So Many Students Using It?

The Duolingo English Test is a modern alternative to traditional language proficiency exams like TOEFL and IELTS. It was originally developed to help students who lacked access to in-person testing centers. But since the pandemic, it has become a preferred test for over 5,000 universities worldwide — including top U.S. institutions and Ivy League schools.

Why it’s popular:

• 🧠 AI-adaptive scoring that measures real-world communication
• 🌍 Fully online — take it from your home, no need to travel
• ⏱️ Less than 1 hour to complete
• 📈 Results in 48 hours (or less with DET Study)
• 💸 Lower price point compared to TOEFL and IELTS

It’s fast, efficient, and trusted by admissions teams around the world.

👤 Who’s Behind DET Study — and Why Thousands Trust It

The name DET Study might sound like a company — but it’s powered by a real educator: Lance Graney, an American teacher who’s been helping students prepare for the Duolingo English Test since 2017, long before most people even knew it existed.

🧑‍🏫 A Quick Background on Lance Graney and DET Study:

• Taught DET prep in classrooms across Asia for 7+ years
• Helped students attain scholarships and admission to U.S. universities
• Runs a growing YouTube channel dedicated to free DET tips
• Writes detailed blog articles and guides that break the test down simply
• Created a library of AI-scored practice tools, templates, and coaching materials

DET Study is trusted because it’s built by an educator, not a marketing agency.
And it exists to make this test more affordable, understandable, and accessible — especially for international students.

“I made this platform for the students I used to teach in real classrooms. Now it's helping students around the world.” — Lance Graney

💰 What the Duolingo English Test Actually Costs

The test is listed at $70 USD, which sounds reasonable compared to TOEFL or IELTS. But here’s what that number doesn’t tell you:

• You may need to take the test multiple times to reach your goal score.
• If you're rushing to meet a deadline, you'll consider paying an extra $39 for fast results.
• Add optional bundles or materials, and your total cost could rise to $100+ per attempt.

That’s not a one-time fee. That’s per try.
And for many students, one try may not be enough.

🧾 Why Official Discount Codes Exist — And Why Most People Don’t Trust Them

During the COVID-19 pandemic, Duolingo expanded partnerships with educational platforms to distribute official coupon codes — especially for students who had limited access to payment systems or testing support.

DET Study was one of the first trusted partners to make these coupons available alongside actual preparation support, not just a promo link.

But there’s a problem:

Many students have been burned by:

• Fake promo codes from forums or Telegram groups
• Shady websites selling “discounts” that don’t work at checkout
• Middlemen charging fees for something they don’t own

That’s why trust matters. DET Study doesn’t just sell a code — it supports your whole test journey.
And every code comes directly from a vetted, official channel.
