Pourquoi "par an" au lieu de "par année" ?

I presume it’s the speaker, but the speaker sounds female. 

This lesson distinguishes between the use of "en" and "l'". It gives examples of both but fails to provide any information about which one is appropriate and when. One of the comments says that they are interchangeable - which makes no sense as the tests insist they are not?

In "Personne ne croit en toi comme j'y crois", why "y" if y is standing for "en toi?" I thought y was for prepositional phrases beginning with à

Is it the case that “sous jacents” must be hyphenated, i.e. “sous-jacents”?

Bonjour! In French, how do you know in math equations when to use "font" or "égale" for equals?

I had to complete a worksheet where it marked me wrong for writing "Neuf cent soixante-six moins trois cent quarante-deux font six cent vingt-quatre." It told me the right answer was the exact same sentence, but with "égale" instead of "font."

However, it marks "Deux cents plus trois cents font cinq cents" correctly.

Can someone please explain why and when to use each word?

Will you please explain the meaning  of pouvoir in imparfait.
I Can not completely understand its meaning? 

I was wondering why "en" is not accepted in my answer using the phrase "etre au courant"?  You have "of it" in the English hint. 

....sans que Neve en soit au courant

Is there any logic why jusque is sometimes followed by à and sometimes not? Like here it's jusque-là but otherwise you've got something like jusqu'à maintenant...?
