So, is it incorrect to say - Debo comer- Is the use of deber covered in other lessons?

Thanks

Can we get an option to remove hints from the tests?

For example with the following hint: 

HINT: Conjugate “ser” in El Pretérito Imperfecto

There is really no point to the question, because I can easily conjugate the verb if you tell me this...the difficulty is in knowing when to use the imperfect vs the preterite.

I would also like an option to get rid of the multiple choice answers for the one or two word answers. Sometimes you can eliminate three options just based on context without actually understand the grammar that is supposedly being tested.

Right now it is too easy to get the right answer when you don't really know the topic very well.

The question given is: De los dos películas esa es la peor.

The multiple choice answers are

Out of those two films that one is very bad /  better / bad / worse.

Since película is à “feminine “ noun; Should the question not be De ESAS dos películas esa es la peor. Or perhaps De LAS  dos películas esa es la peor.

Luis told me where he had gone on holiday. : Luis me dijo ___ había ido de vacaciones.

The stated answer is “dónde” (with an accent), but this usage seems to be that of a relative pronoun. What am I missing? Why is it “dónde” (with an accent)
