Learning While You Sleep
I read this article today http://tinyurl.com/cuormfs. I was wondering if there is way to listen to Spanish similar to this in Duolingo or elsewhere?
Sounds like "Brave New World" lol.. I am sure it works more effectively on different people.. Just try it and find out if you are one of those people, but bear in mind that it has to be said to you in your sleep for a prolonged period of time... Months, maybe years, for it to sink in... I think memrise is the way to go... http://www.memrise.com is awesome in every way at helping you remember your vocab. I recommend the 5000 Spanish word course.
The Android VT app also has a sleep mode:
