RC99 is quite a good book. Just see the "GMAT Experience" thread. Almost every other post recommends using RC99 for practicing Reading comprehension
Are there different versions of RC99. I already have this pdf ...bought it from my friend at the lower price. I am also aware that this book was available for free on Aristole website when Aristole were staring to promote their products.
The paid version of this book is the same one as the one that was available for free ? Please let me know.
thanks in advance.
