While finding GMAT sample tests should not be a problem for those of you who have bought our course, if you chose the more onerous task of free GMAT preparation, you may have hard time finding enough GMAT sample questions to get sufficient practice. If you go to your local bookstore or library and look for information on the GMAT test and sample questions, you will find valuable information, but you should be fully aware that the GMAT sample questions that you see will be out of date. 
These questions change on a regular basis, primarily because so many people are now studying for them, and therefore you need the latest information so you can make sure you are studying the most current questions.
The amount of time it will take for you to study for the GMAT will likely depend on how you have scored and performed in previous standardized examinations as well is how confident you are of your skills and knowledge right now.
The main problem with finding free GMAT sample questions is that the questions you find may not be representative of the GMAT questions; there just aren’t enough good ones. We have some GMAT sample questions on our website (see links below), but to get more, you should buy the Official Guide for GMAT Review. The book is reasonably priced (around $20 on Amazon) and contains 800+ GMAT sample questions that have been used on the GMAT. For those of you who plan to invest in your GMAT preparation, we offer 4000+ GMAT sample questions that can be used to generate hundreds of GMAT sample tests using our Test Generator.
If you have taken a practice test and you have already scored well, then you may not feel that additional studying or Gmat sample questions are a valuable use of your time. No matter when you plan to take the GMAT, you need to study the current questions. There is only one GMAT prep study program that is considered to be the most highly respected preparation and practice test programs available. When you purchase this GMAT prep program , you will get unlimited access to 100% of the study materials. This includes sample videos, various problem sets, and even advice on how to take the test in the best possible way.
