I noticed a few mistakes here in this lesson. In some areas, for the "tu", "ellas/ellos", and "nosotros/nosotras" forms of "acaber" there are double "ba" syllables. For example, there's "acababas" instead of "acabas", "acababan" instead of "acaban", and "acababamos" instead of "acabamos". I've double checked elsewhere to verify the correct spellings of these forms and nowhere else did I find the double "ba" syllables.

Hello! Unless I am missing something, I was provided a question in the drop-down where I had to pick the correct conjugation of tener with the imperfect subj. It seems to be that both tuviera and tuvieses should be accepted, however only "tuviera" was. If tuvieses is not accepted, it should not be listed in the drop down. Perhaps you can fix this? Gracias.

During the quizes, it translates it into english without asking me. I'd love to have the option of not having the english there as it takes away learning opportunities. Can I remove it? 

The answer appears to treat estar as a verb like gustar.  It doesn´t appear as such in your list.  What am I missing?

Hi, I'm wondering if you can use this construction in cases where the "future time indication" is implicit.  For example:

    ¿Vas al concierto?

When both participants know that "the concert" is going to take place next week.  If that's not incorrect, does it sound more or less natural than "¿Vas a ir al concierto?" ?

Thanks!

So can i use que and cual interchangeably eg 
Mis vecinos, quienes tienen tres hijos, son muy ruidosos.

Mis vecinos, que tienen tres hijos, son muy ruidosos.
