Bonjour, Est-que c'est une règle pour l'utilisation de mille neuf cent vs dix-neuf cent pour 1900 ? Bonne journée, Paul.

The question and answer: J'ai fini. - Write "I didn't finish." : Je n'ai pas fini
makes me wonder... In English 'I have not finished' implies you are still working on it, whereas 'I did not finish' implies that you are not still working on it (e.g. you ran out of time in an exam). It looks as if the passé composé could mean either of these. Right? If so, what is the easiest way to make this distinction in French?

I have read that if the subject of the secondary clause is the same, that one should not use the subjunctive, instead just use the infinitive.   But i have a sentence where i'm trying to figure out how to do that even though it feels like the subject has to be restated and would require conjugation.  I'm trying to say "Sometimes I feel like i don't know any french", and here's what i've come up with.  Would be great to get some guidance on this, perhaps there's a better way to construct the sentence.  Merci!

Parfois, je me semble que je ne sache aucun de francais.

What is the difference between 

Il fait froid hier soir       And

Il faisait froid hier soir

The translation is identical and the lesson doesn’t clarify it.
