Hi, and welcome to the forums! Here is a good place to start:
best-gmat-books-reviews-recommendations-for-your-prep-77703.htmlAnd here is a list of guides and question sources that will help you to perform well on the GMAT:
QUANT:1. Manhattan Math Series - Purchase all five math books. This is all you need to grasp the concepts.
VERBAL:1. Manhattan SC - The best SC guide available.
2. Powerscore CR - The best CR guide available.
QUESTION SOURCES:1. GMATClub Tests - Simply put, the hardest practice questions available.
2. Jeff Sackmann's math sets - Questions of the highest quality.
3. OG Quant, Verbal, and 12th edition - Necessary, but not enough for a 700-plus score for most people.
4. GMATClub Forums - Thousands of high-quality GMAT and LSAT questions, along with explanations. For free too!
5. Test Simulations - The best are GMATPrep and Manhattan, in that order. If you purchase any Manhattan book, you can access six online CAT's for free.
ADDITIONAL RESOURCES: (not necessary)
1. Powerscore LR - Only for those who are truly weak in CR and can spare the extra time and money.
2. Powerscore RC - Only for those who are truly weak in RC.
3. LSAT SuperPrep - Excessive, but this book contains 100 RC and 150 LR questions for a reasonable price.
Your dilemma, however, is internet access. This may pose a problem for GMATClub and Jeff Sackmann's resources, as well as the CAT's. One thing for sure, though, is to save the
GMATClub Tests and one GMATPrep test for last. And while I love Jeff Sackmann's questions, if you find them too expensive or difficult to access, don't worry. The
OG and
GMATClub Tests should be enough.
I also included some LSAT material, but these are not necessary for a high score. However, the SuperPrep might appeal to you if internet prohibits sufficient online practice at GMATClub.
