Hey! Why in the examples is it  "j'ai de chance" and not "J'ai de la chance"?

So if I want to say "she is truly great", should I use "vraiement" or still "vraiment"? 

Can puis be used instead of ensuite. As this was not presented as a correct alternative.

mais 'puis' je me suis réveillé, et ce n'était qu'un rêve !

Some of the examples and test answers of used to + reflexive verb use avoir l'habitude de  and some dont.  I cannot find any explanation for this.

Does the word intensivement not exist in French? I used it in a test and it was marked incorrect and intensément given as the correct version.
 

I was taught (in both English-taught French classes and by French-speaking people) that the use of 'on' for 'we' was very colloquial and borderline bad grammar. I was baffled by the construction of the sentence using 'we' in English. I'm annoyed to be classified as 'lower intermediate' when I am considerably more advanced than that, even if I'm out of practice. I need to practice, but won't get much if I'm getting questions at this level and being challenged only by a confusing usage.

Mon dictionnaire (un Robert) dit que l'adjectif "vidéo" est invariable, mais vous avez écrit "vidéos".  Je suis perplexe!

When is tôt used versus En avance?

Also pile versus a l’heure ? 

How do these words differ in their usage?
