Spanish language Q&A Forum

Hola

I am having difficulty understanding when an answer is simply incorrect and you wouldn't say it in Spanish, and when the answer given is not what Kwiz expects to see.   For example, I wrote 'Cuando fine la leccion' (I can't find the accent!) and it was marked incorrect.  Would it be incorrect to say that in conversation with a Spanish speaker?

Many thanks

Hola…..¿por qué se usa el imperfecto de subjuntivo con una oración que empiece con “No sabía que_________”.  No entiendo el “trigger” en este caso.

I reported this as an issue, and perhaps should have brought it up here instead. For one of the quizzes, the answer is 

A veces __me olvido de__ que llevamos casados 20 años. (Sometimes I forget that we've been married for 20 years.)

I noticed that the verb *olvidar* is being used intransitively and that, even though the "accidental se" is being used, that olvido is not in the third person. (It's not in the preterite / no accent on the o). I'm having trouble finding an example of this on the lesson page. 

Thanks!

In question 39: can it also be, "vamos a tener," or is it only "tredremos?"

In the example "A veces ________ que llevamos casados 20 años", why is simple olvido wrong? - when there was another question in another kwizz about forgetting a towel, and olvido was correct. How are we supposed to know if something is accidental or not? I must say that I find this lesson absolutely confusing and no matter what I put in the answer, it always seems to be wrong. 

(And I notice that it lists me as C1. I'm not C1, I am still struggling with B2. The Kwizbot doesn't understand the fluctuating nature of how people learn, forget, re-learn, get wrong again, and so on.)
