How to start for gmat test

One should take around four to ten weeks for test preparation. Preparation can start with taking a power prep sample test. Power prep sample tests are very close to official gmat exam. So when you take this sample test without much preparation then this will provide ample idea about your current level and gap between the current level and desired score. Analyse the mistakes done in the sample test. Identify all the strong and weak areas. Later you should start preparation based on sample test analysis. The best book to start with basics is princeton gmat review book. This book is good to brush the maths basic concepts and english grammer rules. To learn more about the english basic grammer rule also refer the grammer book by wren and martin. There no need to read all the sections from wren and martin. Section one is more than enough and it provides all the basic grammer rules. Normally it takes around ten days time to finish the princeton review book and another 3-4 days to complete the wren and martin grammer book. So one can set two weeks target to finish the basics from these two books. Once you brushed the basic go for another sample test preferable take princeton sample test. Do the through analysis of this sample test. This test score should be close to your target gmat score. If you find unreasonable gap between the sample test score and target score then It is the time to either revise your target score or look for flaw in your basics preparation.
