yes it does..great CR questions...
The explanations for the answers in GMAT 800
seriously need improvement, especially on the SC sections. In OG, the author not only explains well on the right answer, but also on the incorrect answers. Kaplan 800
tends to take readers for granted by avoiding efforts to give readers the holistic approach we need to better learning.
The answers and explanations on the math part is however okay, but not great either.
