Setting up equations IS an issue to me.
If I have the equation already setup in front of me, I will solve the problem with my eyes closed (almost). I really need to learn how to translate problems into equations. Any suggestion / advice?

I am expecting the "Practice, practice" reply, but beside of practicing, which is something I am alreay doing, what else can I do to come closer to perfection... or let's say my target score?

Thanks,

My recommendation would be to review the word problem translation tables that come in most of the books on the GMAT (like the Official Guide or Kaplan). The tables help you decipher word problems quickly into usable equations.

Other than that, I think you mentioned the biggest one: practice. With practice, you'll notice a pattern of question types. The familiarity you gain with these types will help you know how to set them up as equations.

Hope that helps.

Thanks a lot. I have also found an entire MGMAT book dedicated to Word Problems, any comments on that book?

Many thanks,

I'm not familiar with that book. I've completed the Kaplan Math book, and I'm almost done with the Kaplan 800 Quant section. Both have good practice of word problems. Also, Kaplan really hammers you with some basic techniques that help you know the best method to solve problems (like when to set them up, when to plug n' chug, etc.).

Of all my books so far, I've found OGGMAT 11th the least useful for Quant. But of course, that's my opinion.

"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."
