Number and gender

Mutaal, 

which cases are you referring to ? 

Agreement is as per the usual rules for compound verbs conjugated with avoir, as indicated in the lesson, and per the link below.

There is an example included with feminine direct object preceding the verb : 

                “ Tu es récompensé pour l'avoir aidée. 

You are being rewarded for helping her.

 

ATTENTION: 

When using avoir preceded by an object pronoun (e.g. pour l'avoir aidé/e), you need to agree the past participle with the object referred to by the object pronoun! “ 

 

Special cases when the past participle agrees (in number & gender) when used with 'avoir' in the compound past in French (Le Passé Composé)
