Answer Question
Speaker didn't say "en"
I didn't know where else to put this issue. On Level 2 Session 21 in the "Write the phrase you hear" section when he says "La semana pasada, estuve en México" it's almost impossible to notice that he says en. I know grammar wise there is supposed to be an "en" there and I should have thought about that, but it's still frustrating. If there is a better place to report these types of speaker/audio issues let me know. :)
