In the lesson you give examples for estar deseando in imperfect, but not for tener ganas de. I feel pretty sure I could use tener ganas de in imperfect as well, but neither seems to fit well with preterite. 

Could you say more about how these two are used with other moods and tenses and what limitations, if any, exist.

EDIT: Sorry, I see you answered part of this in an earlier reply. However, could you indicate any other limitations that might apply. I wonder about subjunctive too.

I am having difficulty understanding the difference in terminology between "impersonal se" and "passive reflexive se" and in particular the difference in their translation into English. ¿Puedes ayudarme?

- Ella cree que habrá consecuencias.

- Creía que era una bicicleta por participante. 

Because the subject in the two examples above believed/thought that …(creer que) …, I would have used the subjunctive in the second clauses. I equated this to querer que and esperar que both being followed by the subjunctive. What am I missing?

What prepositions can be used with creer and how do they change the meaning.

Creer en/a ...

I think I understood this except, but I'd feel better if there was a translation, too.
