As a 3rd year Russian major who slacked off & didn't study over the summer, I found this book perfect for quickly relearning everything I'd forgotten.
Best Book for Russian
This is simply the best book I've found, and there have been many. Also, it is small. And concise. I keep giving my copies away to Russian instructors who use it also. I am an intermediate level student and have been living in Russian for 3 years. I wish I had found this sooner.
