Could someone explain to me why sometimes "it is" has a gender in French? For example:

Tu aimes l'école ? C'est très intéressant.
It is = C'est

Tu aimes ma voiture ? Elle est très rapide.
It is = Elle est = feminine.

merci!

Answer

I'm a French learner rather than a French speaker, but I've encountered this before.

Sometimes one uses the construction:

Il est . . .      Elle est

Other times one uses:

C'est

I've been working at learning French for years, and still don't know the difference right of the top of my head.  I suggest googling (or searching in YouTube):

Il est or c'est

You should find a lot of information.
