i'm working through the OG12
and now i have looked up the solutions for some exercices. I have noticed that the explanations are quite complicated. If i look at my solutions (or at the solutions in the forum) the include just a few steps and in contrast the solutions in the book take up a lot of steps. Why is it so complicated ?
Do anyone knows some good books with good GMAT Questions between 700 - 800 ? Thanks!
