On page 76 PS problem #12, can someone explain the answer 3T + (4T+1). I don't understand were the 4t+1 comes from? The other text and video don't show how the book arrived at this answer, thanks.

Please post the question in its entirety.
Most of us don't have an OG10 kicking around

Cheers,

It's probably also a good idea to get a new version: the test is so different now that OG 10 won't prepare you as well as it once did. You WILL be introduced to a lot of the fundamental ideas that recur on the test, but you WON'T see most of the new topics of emphasis, and you'll get so much less value for time.

"Target Test Prep is the closest to the official version of the GMAT exam, about 99% accuracy in terms of the quality and quantity of information. The course has excellently created singular sets of focused lessons and tests for every possible topic that one could come across in the official GMAT exam."

"The TTP course maximizes the efficiency of the time you spend studying. It will take time and effort but I could almost guarantee that if you complete the course exactly as it is laid out you will get an amazing score. They also have a very responsive team willing to help with any questions you might have."

"TTP has two things that I think no other test prep company offers: A teaching approach that reinforces understanding and an attitude that will give you the mental preparedness needed to succeed on the test. TTP gives you a deep understanding of the concept you need to know while teaching you how to think."
