Hello readers, welcome to DET Practice. Today, I will introduce some tips about the Duolingo English Test (DET) for everyone. I hope that through these tips, you all can gain a better understanding of the DET and achieve good results in this exam.

Next, let’s look at some things you should know before the exam:

What is the Duolingo English Test?

Simply put, it’s an online English proficiency test that can be completed in about an hour. Being an online test, it can be taken anytime and anywhere (yes, that includes your bedroom). As a measure of English proficiency, it has been recognized by thousands of universities around the world. This means if you’re not an English native speaker, you can use the score report from the Duolingo English Test to prove your English ability when applying to your desired universities. Compared to traditional TOEFL and IELTS exams, the DET offers a great deal of flexibility. Firstly, you can freely choose the time of your exam. Additionally, in terms of cost, the Duolingo English Test is more affordable. You only need to spend US$59 for one exam. If you choose to buy two exams at once, you can spend US$98, making the price per test even lower (US$49/test). Overall, it’s a flexible and economical English language proficiency test.
