I am seeing progress on these B2 listening exercises now that I keep an eye on the vocabulary list while listening to the entire passage read aloud several times. (Also, it is helping me to repeat the phrase aloud before starting to type it.)  I'd like to suggest you include "lame" and "le manche" in this vocabulary list because they are also words of a somewhat specialized nature.

I'm confused why the response given is : "nous allons aussi nous inscrire à la gym." Shouldn't it be "nous allons aussi nous inscrirer à la gym" with an infinitive in the same way that the alternative choice is "nous allons aussi nous abonner à la gym"?  

"Elle est soulagée de ne pas devoir être opérée."

Is this the infinitif passé, please?

And if not - what!

Could anybody help me with the form of the word: 'cochant'?

I have learned third person plural conjugation is cochent, but this word 'cochant' I couldn't find in a dictionary. 

As you know, cocher is infinitive form of verb but what about cochant? Please!

The original context: "Répondez aux questions en cochant la ou less bonne response."

Please help me!

Why do I see people say "Quel/Quelle est la/le ........?" but in this exercise it is mark wrong?

Just wondering why convenir is conjugated with vous as 'vous convient'.  Shouldn't it be vous convenez?  Please clarify.  Merci!
