DET Practice Promo Codes & Coupons November 2026

solid for writing practice

grabbed the Writing Practice Questions again, really good as usual, though pronunciation feedback was a bit slow today.

Super helpful for the DET!

The DET Strategy Ebook really helped me understand the exam format better. I also looked into their 1-on-1 Tutoring, and it seemed like a solid option, though I didn't end up needing it. Applying the promo code at checkout was easy, and I appreciate that they have a refund policy just in case.

Good, but could be clearer!

i picked up the Grammar Correction Service last week to help with some tricky essays, and it totally helped! the corrections were super useful and definitely improved my writing. i'm thinking about getting an institutional license for my study group too. the only thing i found a bit confusing was trying to figure out the difference between the free and premium plans. it wasn't super obvious on the site, and i had to dig around a bit. once i figured it out, it was fine, but a clearer comparison would be awesome. overall, a good service, and i'll probably shop here again, but a little more transparency would be great!

Spot on with predictions, super helpful

grabbed the score prediction report again last week, mostly because i needed a solid benchmark before my actual test. like my past experiences with DET Practice, the accuracy was really consistent. it was within 5 points of my official duolingo score, which is exactly what i've come to expect from them. i also did some of the interactive reading practice this time around, and it helped me catch a few common mistakes i usually make. used a code at checkout, easy as always. for about 20 bucks, you can't beat that kind of reliability.

Good for the price, mostly

Looking for DET practice? I checked out their Question Bank. It's pretty solid and has a good variety of questions. I also got the Mock Test with Human Feedback, which was helpful for seeing where I needed to improve. Applying the coupon code was easy at checkout, no problems there. My only minor gripe is I wish there were a few more advanced grammar questions. Still, it's a good deal compared to something like Magoosh or Preply.

Really solid prep, minor quibble

got a decent 20% off for the Institutional Licenses, which was a sweet deal for my study group. the codes worked fine at checkout, no issues there. i really liked the Sample Answers Guide, super helpful for seeing what they're looking for. my only minor gripe is i wish i could retake the mock exams more than once without resetting everything, just to practice specific sections. otherwise, it's a great tool, way better than some of the other platforms i've tried like Preply.

Good prep, minor issue

was looking for updated questions for the DET and found DET Practice. the Full-length Mock Exam was really helpful and felt current, plus the AI Correction Service gave some solid feedback. just wish they made it clearer where to add referral credits for upgrades, felt a bit hidden when i was looking to apply mine.

ai correction speed is my only gripe

anyone else use DET Practice? the writing practice questions are pretty solid, and the score prediction report was super helpful. but man, waiting for the AI correction took a while, like 30 minutes sometimes. i mean, it's worth it for the price, but kinda slows down practice when you're on a tight schedule.

Another solid order from DET Practice!

Used a coupon for about 20% off my Read Aloud Practice purchase, and it worked perfectly at checkout, as always. I've bought from them a few times now, and their materials are consistently high quality. My only tiny nitpick is I wish they offered more clarity on their refund policy upfront, but overall, super reliable.

So worth it for DET!

Anyone else totally loving DET Practice?! The Mock Test with Human Feedback was seriously spot-on, and the detailed feedback was super helpful for figuring out what I needed to improve. I saved 20% with a code at checkout, and I'm definitely shopping here again! Tell your friends!
