How Lumini helps with DELF prep
You're working on a DELF B2 writing task on your Mac — a lettre formelle arguing for improved public transport in your city. You need to use appropriate formal structures, demonstrate B2-level grammar (subjunctive, conditional, complex relative pronouns), and organise your argument logically. You've written a draft but you keep defaulting to simpler A2/B1 structures because you're not confident with the advanced grammar.
Lumini sees your letter on screen. Hold Ctrl+Option and ask "How can I make this more B2 level?" Lumini scans your text: "You've written 'Je pense que c'est important' twice. At B2, use: 'Il me semble primordial que les autorités prennent en compte...' — notice the subjunctive after 'il semble que' and the more sophisticated vocabulary. Also, you haven't used the conditional at all. Add: 'Si la municipalité investissait davantage dans les transports en commun, les embouteillages diminueraient considérablement.' That's a si + imparfait → conditionnel construction that directly signals B2 level. I'm pointing at each sentence that could be elevated."
The DELF scoring grid
Every DELF task is scored on explicit criteria. Lumini teaches you what examiners look for: "Production écrite at B2 is scored on: respect de la consigne (did you address all parts of the task), capacité à présenter des faits et à argumenter (logical structure with introduction, development, conclusion), cohérence et cohésion (use of connecteurs logiques like 'en outre,' 'néanmoins,' 'par conséquent'), and compétence linguistique (grammar range, vocabulary, spelling). You have good argumentation but your connecteurs are repetitive — you've used 'aussi' three times. Vary: 'de plus,' 'en outre,' 'par ailleurs,' 'également.' I'm pointing at each repetition."
Production orale — the monologue
The DELF speaking exam includes a 5-10 minute monologue on a given topic. Lumini helps you prepare: "Your topic is 'le télétravail.' Structure it: Introduction — define the topic and state your plan. Development — advantages (flexibilité, équilibre vie pro/perso), disadvantages (isolement, difficulté à séparer vie pro et vie privée), your personal opinion. Conclusion — synthesise briefly. The examiner is listening for: clear structure, B2 grammar markers, and your ability to express and defend an opinion. Don't just list facts — say 'je considère que,' 'à mon avis,' 'il me semble que' to show you're giving a personal perspective, not just reciting."
Example questions to ask Lumini
- "Is this subjunctive or indicative — and why?"
- "Have I used enough connecteurs logiques?"
- "Is my register consistent — formal or informal?"
- "What grammar structures would make this more B2 level?"
- "Am I missing any part of the task instructions?"
