Thank you jinkev,
What I am doing right now is doing a lot of look ups in Wikipedia and the internet in general to refresh many concepts and laws. Will the MGMT guides eliminate that? That is, will they be my only source for understanding the basics and theories aside from practice questions. I know that I will need to look up more resources for test practice.
I personally think that you only need the MGMAT guides
. If you are also rusty in math, you can get the MGMAT math foundation book. I am not planning on getting any other books as I believe that MGMAT guides
are more than enough. As for your concern, yes they do cover all concepts and laws that are tested on the GMAT. They even have advanced sections which can give you the upper edge on the exam. There are, however, many other books available on the market which are also wortwhile to take a look at. See this thread :http://gmatclub.com/forum/best-gmat-books-77703.html. You can read the numerous reviews on amazon to have a better idea of the strength and weaknesses of each. But again, if you are just starting and looking for a thorough coverage of topics covered in the exam, investing in the MGMAT guides
is the way to go. By the way, you also get access to 6 CATs when you purchase the guides.
