As a TESOL certified English teacher and cofounder of DET Practice, a Duolingo English Test prep platform, I've dedicated my career to helping students achieve their English language goals. My expertise in English language instruction, combined with a deep understanding of the Duolingo English Test format, has allowed me to create a platform that serves over 400,000 students worldwide.

At DET Practice, we've developed comprehensive resources including our extensive question bank with 18,000+ practice items, realistic mock tests, and innovative AI-powered correction tools for speaking and writing. My teaching philosophy centers on providing personalized, adaptive learning experiences that address each student's unique needs.

Having witnessed firsthand the challenges many face when preparing for English proficiency exams, I'm passionate about making quality test preparation accessible and effective. I take pride in our platform's 4.8/5 rating from over 850 reviews, reflecting our commitment to excellence in English language education.

We look forward to helping you on your journey to Duolingo English Test success!
