Would another way of explaining the difference be to say that in English you could get the meaning of  the imperfect by saying "The teacher [was] opened[ing] the door" and the indefinido as "The teacher [had] opened the door"

But in this specific example of the Preterito Perfecto Subjuntivo....

Cuando hayas hecho tus deberes puedes ir a jugar fuera. 

Is it incorrect to also use.....

Cuando has hecho tus deberes puedes ir a jugar fuera. 

Just curious if they are interchangeable in their use. Thank you.

Thanks you

A question in a quiz asked No es bueno beber ___________ alcohol. The answer was tanto but I chose demasiado. don't they both essentially mean the same thing? Or is there a distinction in Spanish? Thanks

and pretérito perfecto compuesto (twice) in the same lesson for the same verb form. Is it possible to use just one. 

Also, in my experience, ha invitado has usually been translated as has invited rather than invited/ ha visto as has seen rather than saw.   So, I would then translate había visto as had seen. This is very confusing.  Help. K
