Wou! How much time did you input to collect all on one? )
Guys. Stop giving this guy any kudos for this post. This is all copy-righted material. These are the quantitative notes of Maple Leaf Intl. This is a registered GMAT prep school known as MLICETS out of New York. The prep school sells these notes to its students. The poster got his hands on the document from one of the MLICETS students and has uploaded it to this forum (which is forbidden on the forum).
Even the uploaded document states the following:
