When might one use "siempre que" in place of "con tal de que" to mean "as long as." I found the question a bit confusing because it appears that there are two correct answers. Thank you so much, Inma.

Hi Can you please explain why - "I don't know if I will see him again" is not subjunctive, because it is all so uncertain.

Thanks

Are por qué no/ mejor no only used with vamos? Or are these phrases more commonly used for all commands (not just ir)? 

For the road signs, are they third person singular for affirmative commands, and third person plural for negative commands? Or are both singular and plural third person used equally for either negative or affirmative commands?

En verdad no hay cartas horizontales, sino hay cartas colocadas horizontalmente. me suena mejor usar el adverbio que un adjetivos. 

This is more of a comment than a question: I thought it was common knowledge that the best way to retain the information being learned is to practice it. Practice, practice, practice. Yet after I see my study plan and I'm offered the opportunity to "quiz this now", the quiz does not go over the material in the study plan. If I see that material again it is incidental. Why not give two or three quizzes on the same material immediately following the introduction of new material/study plan?? I, for one, need that. Doesn't everyone??

Does "nearly right" mean that one of the other choices was better, or are they all equally right?
