Spanish 60-Second Grammar Workouts
I asked her how she liked it.
“It’s great,” she replied. “These little mini-quizzes help keep me sharp on things like the past tense and imperative when I don’t have much opportunity to speak Spanish.”
I borrowed her book and it does look pretty good for reviewing, remembering and solidifying grammar knowledge, particularly for advanced-intermediates.
Personally, I wouldn’t buy it though. I prefer to do all my grammar practice with the Verbarrator. But, hey, variety is good too!
