Math Proof Studio vs LëtzPass

Math Proof Studio is a proof-writing notebook built around ownership of your reasoning record. Write in a text-first editor, preserve every revision in a linked chain, and run deterministic protocol checks (not grades). Curate selected work into exportable Evidence Packs for sharing or archival.

Prepare for the Luxembourg Sproochentest naturalisation exam — the oral test you sit to qualify for Luxembourgish citizenship. LëtzPass is built for adults who don't want to walk in unprepared. It mirrors the real exam format: a five-minute picture description followed by a five-minute topic conversation, then a 25-minute listening comprehension test. You practise the same way you'll be tested. WHAT YOU GET • 17 exam topics with 350 model questions in Luxembourgish — every question is one you might be asked • 20 picture-description scenes with the four-step framework that works for any image prompt • Full mock exams scored against the real B1-equivalent rubric — pass at average ≥ 50, or oral > 50 • Pronunciation feedback after every answer: transcript, score, and a model answer to compare against • A study plan paced to your exam date — Sprint, Standard, or Comfort HOW IT WORKS 1. Pick a topic. Read the prompt. 2. Tap to record your answer in Luxembourgish. 3. See your transcript and a model answer side by side. 4. Try again, or move to the next question. The picture-description framework and the topic question bank were built and validated by native Luxembourgish tutors with deep experience preparing students for the Sproochentest. No fluff, no filler — every chapter is one a tutor has read. WHO IT'S FOR • You failed the Sproochentest and don't want to walk in unprepared again • You understand more Luxembourgish than you can say under pressure • You want focused practice without sitting in a classroom • You're starting from zero and want the fastest affordable path to exam-ready speaking PAYMENT LëtzPass offers Sprint (4 weeks, €59), Standard (12 weeks, €119), and Comfort (24 weeks, €159) as one-time in-app purchases.
