Common mistakes
1. Using the infinitive instead of a conjugated form
✗ Wrong: “Je conclure le projet.”
✓ Right: “Je conclus le projet tous les jours.”
The infinitive conclure never takes a subject. After je you need the conjugated present form conclus.
2. Using the wrong person
✗ Wrong: “Je conclus le projet.”
✓ Right: “Je conclus le projet tous les jours.”
conclus is the tu form, not the je form. The je form is conclus — check the person before you write the form.
3. Using the present for a finished past action
✗ Wrong: “Je conclus le projet hier.”
✓ Right: “J'ai conclu le projet hier.”
Hier points to the past, so use the present perfect ai conclu here, not the present conclus.
4. Mixing up the stem in the stressed forms
✗ Wrong: “Je conclusons le projet.”
✓ Right: “Je conclus le projet tous les jours.”
conclure is irregular in present, passe-simple, present-subjunctive, imperative-affirmative, imperative-negative: those tenses do not follow the regular -re pattern, so learn them as a set rather than guessing from the infinitive. The other tenses follow the regular pattern.
5. Using the wrong auxiliary in the passé composé
✗ Wrong: “Je suis conclu le projet hier.”
✓ Right: “J'ai conclu le projet hier.”
conclure takes avoir in the compound tenses, not être: ai conclu, never the être form.
6. Using the indicative after a subjunctive trigger
✗ Wrong: “Il est important que nous conclusons le projet.”
✓ Right: “Il est important que nous conclusions le projet.”
After il est important que French needs the subjunctive, so use conclusions here, not the indicative conclusons.

Second, learn the passé composé with its auxiliary: ai conclu shows the pattern, and the participle conclu is the same in every perfect tense. Third, add one new tense a day, always in a sentence, and test yourself the next day before you learn the next one. A verb you can use in a sentence is learnt; a verb you can only recite is not.
