como crear tarjetas de flash mis `proprias tarjetas personales

Me gustaria crear mis proprias tarjetas de flash para estudiar vocabulario

Ya no es posible crear tarjetas de flash personalizadas en este programa. 

You can review each lesson's flashcards. You can review your saved vocabulary (but get no points for this, if points are important to you). You can export saved vocabulary to create your own flashcards.  I use ankiweb.net for this - it is a free desktop/laptop program which has a large amount of community resources or you can create your own. There is a droid app that is free (I think) but you have to pay for an iPhone app (if you want to use it on an iPhone). Hope that helps!
