Hi, I'm pretty new with the company; so, I can't speak from experience. However, I've been talking to a lot of customers over the last few weeks - many of which have told me that it has worked great for them. The only addition they say is really helpful to them is prep-testing; which you could purchase through us as well.
One more thing; I had a couple of customers tell me that the R2 updates were a good part of the exams and they wished they had done the following series as well . . .

Just a thought. Hope this helps.
