On Friday, while walking home from work, I finished listening to Harry Potter i Więzień Azkabanu (the 3rd Harry Potter book in Polish).  This is the first one where I had both the text and the audio.  I tried doing a couple of things with this:
- Simultaneous reading and listening.
 
- Listening then later reading.
 
- Switching off, doing which ever one I feel like at the time.
 
#1 turned out to be waaay harder than I thought.  I read at a different speed than the actor read the text.  I kept wanting to pause the audio so I could catch-up.  This turned out to not be very enjoyable for me.  #2 worked great, although it was a little boring at reading time.  There would sometimes be a word or two that I failed to catch in the listening that the later reading would clarify, but nothing that ever changed my understanding of the text.
