Hi guys

I have done about 100 PS questions on the OG 11th and 12th edition. After analysing my answers, I see that my weakest area is "operations on rational numbers". I do not like this trend as a lot of the questions on the GMAT test touches this area.

I would really appriciate if you guys have some tips on how to improve in this area. Can you recommend some great books, webpages or similar? And do you have some tips on how to think and approach these types of questions?

Thanks a lot!

Hi Jimmy,

I think you would find the OG Companion very useful. I mean the one from gmatfix, not mgmat. it's great at teaching take-aways and multiple solving approaches and guessing strategies to the questions in the OG. run a search for "gmatfix official guide companion review" to help make up your mind. it's a great book

Thanks to the both of you!

1) I do have the MGMAT Number Proporties, so I will definetely go through this one more time.

2) Great tips regarding the GMATFIX companion. I do have the MGMAT companion (but not a big fan), so will have a look at the one you recommend to see if there is anything I can pick up. I am sure there is

"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."
