I have studied Russian for three years, but unfortunately, because I am graduating, I will be unable to take the advanced course that my college offers. For the past couple of months, I've been trying to find a good package so that I can learn Russian on my own. Out of all the ones I have explored, Pimsleur looked to be the most promising. While it did help me in that I am able to speak more clearly, I don't see it as being a replacement for an advanced Russian course. For one thing, the vocabulary is extremely limited. It will help you have casual conversations, but don't expect to be having any deep discussions about complex subjects. Two, because the reading supplement is so limited, many problems will arise when you have to write. Three, and most importantly, I feel that the speakers speak too slowly, at least compared to the people in the listening supplement of my textbook.
