DELF B1 prep

What B1 actually means

CEFR B1 is the threshold level, the point where you stop being a student of French and start being a user of French. You can hold a conversation about your work, your travel plans, an opinion on a movie. You can read a French news article and get 80% of it. You can write a friendly email or a short complaint. You can survive a week in Paris without resorting to English. Critically, you can do all of this spontaneously, not by reciting memorized phrases.

B1 is also the minimum French level required to apply for French citizenship by naturalisation, which is why it's the highest-volume DELF exam every year.

What gets tested, exactly

The verb & tense scope you actually need

The B1 sample papers and the official France Éducation B1 référentiel are explicit about the grammar scope. For verbs specifically:

Active production (you must produce these yourself, without prompts)

• Présent indicatif across all subjects, including irregular high-frequency verbs (être, avoir, aller, faire, dire, prendre, venir, voir, savoir, pouvoir, vouloir, devoir, mettre, partir, sortir).
• Passé composé with correct auxiliary choice and past-participle agreement. The 14 être verbs (DR & MRS VANDERTRAMP) cold.
• Imparfait with full distinction from passé composé. This is the biggest grammar test of B1.
• Futur simple for plans and predictions.
• Conditionnel présent for polite requests (je voudrais, pourriez-vous) and hypothetical statements.
• Impératif (tu, nous, vous) including pronominal verbs (lève-toi, asseyons-nous).
• Periphrastic tenses: futur proche (aller + infinitive), passé récent (venir de + infinitive), présent continu (être en train de + infinitive).

Passive recognition (you should understand these when you hear/read them; basic production accepted)

• Subjonctif présent after the most common triggers: il faut que, je voudrais que, bien que, pour que, avant que. You'll get bonus points for using one in writing; you won't lose points for avoiding it.
• Plus-que-parfait in reading texts. You won't be required to produce it.

NOT tested at B1

• Subjonctif passé · Conditionnel passé · Futur antérieur · Passé simple · Subjonctif imparfait.

The four B1 verb mistakes that cost you points

1. J'ai allé instead of je suis allé(e)

The single most common B1 oral-exam error. The être verbs are a closed list of 14 (plus pronominals): aller, venir, arriver, partir, entrer, sortir, monter, descendre, naître, mourir, rester, retourner, tomber, devenir. Memorize them by group (DR MRS VANDERTRAMP) or by mental image (a journey: arrive, enter, go up, stay, come down, leave, return, fall, are born, die). Drill them in passé composé until j'ai allé physically sounds wrong to you.

2. Past-participle agreement

Three rules to internalize: (a) être verbs agree with the subject (elle est allée, ils sont partis); (b) pronominal verbs agree with the reflexive pronoun when it's a direct object (elle s'est lavée, but elle s'est lavé les mains); (c) avoir verbs agree with a preceding direct object (la lettre que j'ai écrite). B1 only tests the basic cases, but the basics are where most candidates leak points.

3. Imparfait vs passé composé confusion

Forget "imparfait is for repeated actions." That's a beginner heuristic that fails on real text. The real rule is aspect: imparfait describes a state, a habit, or the setting of a scene; passé composé describes a discrete event that happened. Test by trying "was/were ___ing" (imparfait) vs "___ed" (passé composé) in English. Quand je suis arrivé, il pleuvait = "When I arrived (event), it was raining (setting)." This shows up on every single B1 writing prompt.

4. Je voudrais ≠ je veux

Using je veux in a polite request is the verbal equivalent of pointing at things. Je voudrais, j'aimerais, pourriez-vous, these are conditionnel forms and they're expected in your B1 oral. Not using conditionnel at all in the oral production section is one of the fastest ways to score below 5/25 on "morphosyntactic correction."

Recommended timeline (from A2 to B1-ready)

Assuming you're a comfortable A2 (you can handle passé composé in writing, you know the top 50 verbs):

• Weeks 1–4, Imparfait + the pc/imp distinction. 20 minutes a day on imparfait conjugation, plus one paragraph of bilingual narration daily (write a short story in English, then translate it choosing pc vs imp for each verb).
• Weeks 5–8, Futur simple + conditionnel présent. Same stem family, learn together. The "endings" for both are derived from avoir conjugations, once you see that, you stop memorising.
• Weeks 9–12, Subjonctif présent recognition + basic use. Focus on the 6 high-frequency triggers (il faut que, je veux que, bien que, pour que, avant que, jusqu'à ce que) and the 9 irregular subjunctives (être, avoir, aller, faire, savoir, pouvoir, vouloir, valoir, falloir).
• Weeks 13–16, Mock exams. One full past paper per week, timed. Get the writing and oral marked by an iTalki tutor.
• Throughout: 15 minutes of verb drill daily. Not negotiable. Free web tool here or get the app for level-targeted Custom Quizzes.
