Translation of Kausalität

Thanks a lot. Today and tomorrow are holidays in Switzerland, but I'll do it Tuesday first thing in the morning...please have a look at it and confirm. Where do you want me to place a reference?
Now I needed to decide where to go next and I decided to use the information that the girl gave me. I went back into town to the central station and booked a night bus to a place called Palenque.
Let me understand further: If you go through the 'vocabulary builder' in the left menu and choose new lesson it works faster than when you get there through the list of all lessons? Did I get this right?
