practice\strengthen specific words

[Asaf.D]

Is there a way to practice specific words, not 1 word at a time?
There are a few words I feel I'm weak with, and I would like an option to get an ad hoc lesson of those few words.

Hi! Right now, you can't group the words you'd like to practice. We recently updated the way that we calculate word strength, which you can read about here: http://www.duolingo.com/#/comment/486819 We'll continue to add ways for you to practice. Appreciate the suggestion!
