This is duolingo's memrise course: https://www.memrise.com/course/1031737/hebrew-duolingo/
It's extremely helpful, as it has all the same vocab (in order; I'm doing the two concurrently) and the memrise course has audio for every vocabulary word.
I try to stay just a little ahead in memrise so that I've heard how all the words sound before I come across them here on duo. Once in a while I get them here first, then I just memorize the spelling and head over to memrise when I finish. :D
