I am in the process of creating my unique video-course for your Duolingo self-preparation. I plan to have about 60-70 lessons there, and at the moment, 30 series are recorded already.
The tasks that they cover are Read and Select and Read and Complete. Now I am shooting lessons about Fill in the Blanks.
If all is good, I will complete my Duolingo course on the eve of the New Year, 2025. The initial price for the course will be about 139 USD, including several helpful bonuses.
If you wish, you can pre-order the course “DET With Flying Colors” with a huge discount. You will get these 30 lessons and start working, and the rest will arrive to you in portions till the New Year.
If you need to boost your DET score by 10-20 points within 2-3 weeks, write to me and ask for individual private tutoring. You can read the testimonials on this website. As to the improvement of your Duolingo score, I am really beyond competetion.
