Hi,

I've recently been studyn for the GMAT quant with Manhattan GMAT editions and find the word problem book very useful but the problem very hard. Once I read the question if the question gives too many varaibles and constraints my mind get boggled or if it is too simple i am not sure if I am writing out the right equation to solve the problem at hand (except when I look at the explanation I have the equations right but get stuck on how to solve the entire question using those 2 equations. It usually ends up being a question where I have to combine the 2 equations but It doesnt make sense to me why. Word Problems are the hardest for me to translate, is there better study material or a process that will help me? Other than "just focus more".

HELP

You should feel free to post a specific example here. If you walk us through how you thought about a question you struggled with, we can better see where you went astray, and how you might make adjustments to avoid the pitfalls you find yourself stumbling into.

"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."
