I was wondering why it is "les effort physiques" without the noun being plural. I expected it to be "les efforts physiques" ? (with agreement between the definite article and the noun and the adjective)

Qu’en est-il de Julien et Sophie?

I don’t understand the structure of this question. I imagine there is an idiom I haven’t seen before. What is en replacing?  What is il referring to? 

Thanks.

We've been taught here on Kwiziq "n'importe où" but not "qu'importe où." So what is "qu'importe où?" 

Why "m'a gâché la vie" and not "a gâché ma vie"  or "m'est gâchée la vie".

When I have moved up a level, from what I understand Kwiziq will not test me on anything from previous levels unless I switch back to the level.  My general question is this: how often do people review and improve previous levels?  But more specifically:

I think I read on here somewhere that the suggested time to move up is when you achieve 75% in a level. Is it recommended to return often, e.g. every day or two, until getting it up to 100%, or less frequently?

Finally, when lower levels are at 100%, how often is it recommended to return to them? 

Please clarify why in this lesson  the passé composé is used in "Depuis que je t'ai rencontré, ma vie a complètement changé"  but present tense is used in "Depuis que j'ai quatre ans, je porte des lunettes."   Thanks.

Bonjour:)  Would you please review the kwiz answer I missed in the above lesson?  I did not find any of the possible choices for an answer to be particularly applicable.  The actual answer seemed like it was l'imparfait situation in the past so I did not choose that one.  I knew "built" was not a verb used in the choice but it seemed to imply the present tense to me.  Anyway, many thanks for some clarification on this question at your convenience I hope?  Merci.

Can you add an apostrophe and say:

Aurélie is going to eat at her parents'

I wrote  “nous sommes ouvertes” as it was “the Bank” that was giving the information or am I just being too literal here ?
