CertiLang helps people prepare for official German exams: TELC, Goethe, TestDaF, DSH, and ÖSD. Most prep resources teach vocabulary and grammar in isolation, so you're never quite sure what's actually costing you marks on exam day. CertiLang works differently. You start with a short diagnostic that maps your strengths and weaknesses across reading, listening, writing, and grammar. From there you get a study plan built around your actual weak points, not random exercises, along with feedback that explains why an answer was wrong, not just that it was wrong. The free plan gets you core practice and basic progress tracking. Premium (from €9.90/month, less on longer plans) unlocks full mock tests with scoring, unlimited AI coaching, and detailed feedback on your writing and speaking. Every Premium plan comes with a 14-day money-back guarantee.

I found CertiLang while looking for German exam practice online. I really like having reading, listening, writing, and speaking all in one place. The feedback helps me understand my mistakes and what I need to improve. Simple to use and definitely helpful for exam preparation.
I’ve been using CertiLang to prepare for my TELC German exam, and it’s been really helpful. The feedback helped me improve my writing and understand my mistakes. The mock exams are also great for getting used to the exam format. I feel much more confident now!
I used CertiLang to prepare for my German language exam and found it very useful. The platform provides realistic practice for German exams such as TELC, Goethe, ÖSD, and TestDaF, with exercises covering reading, listening, writing, and speaking.
What I found most helpful was the detailed feedback. Instead of simply showing a score, CertiLang helped me understand mistakes in areas like grammar, vocabulary, writing, and speaking so I knew what to improve.
The mock exams also made it easier to become familiar with the exam format and practice under realistic conditions.
I would recommend CertiLang to German learners who are preparing for an official German language exam and want structured practice, mock exams, and detailed feedback in one platform.
