My answer to a question in the quiz wasn't in the dropdown. Please could you explain why the phrase My little boy is in kindergarten uses 'en' instead of mon petit garçon est à l'école maternelle? Thank you.

So how do we use " dans" "en" "à" like they got the same meaning so I'm very confused 

Here it is 

‚c‘est M.Dupont qui était responsable…‘

Is this an expression that always uses the present tense followed by the imperfect? Could you use imperfect and imperfect in this example ……c‘était M. Dupont qui était…..

Thank you 

Leave my sister alone! 

Would Laissez-la! Carry a greater sense of gravity than Laisse-la! ?  

Especially those with "que" followed by noun.
I can still wrap my mind around and understand "Qu'est-ce que c'est?", but "Qu'est-ce que c'est que un stylo", how are they connected with "que"? 

Forgive me if I wrote some sentence wrong, it's really kind of weird for me to remember 😂

But when is it Avoir vs Etre? I cant seem to learn the rule for this

why for past we use -  j'avais du mal 

But future we don't use - j'aurai du mal 

and uses - je vais avoir du mal ?

In the one question they use 'en': "Il s'en souvient. = He remembers it." I don't see anything in this lesson explaining when we would use en with this verb?
