Nosotros todavía no salimos del trabajo.        /We haven't yet left work.

Juan todavía no salió de casa.      /Juan has not left the house yet.

Have coin with letters VMREX on it. What does this refer?

When using de lo más with estar, specifically, is it preferred or more common to have the adjective agree with the subject, as distinct from when using ser for example?

Why is creer not the right verb for "she thought that" . Difference between pensar and creer please? 

Hola. How do express the difference between "The students must not use a calculator" (in the examples), and "The students DON"T HAVE TO use a calculator." which has a very different meaning. Thank you! 

Are ´con tal de que´and ´a condición de que´ interchangeable ?
