Quant from PP, Kaplan, Barrons, Princeton, etc. is not good enough to take you to 165+ in GRE. To get the extra marks you should also focus on other areas. Try to cover the syllabus of Indian MBA entrance exams like CAT, this will give you the added confidence to crack GRE. One to the recommended books will be Arun Sharma (TMH Publications) for Quantitative Aptitude.
Keep special focus on Probability questions, you can do GMAT probability questions/CAT questions/IIT JEE questions. Some distribution questions on normal distributions, number of SD, area under curve, comparing two areas, comparing distance from mean, etc.
DI/Table questions need strategic approach, again Arun Sharma for Analytical Reasoning (TMH Publications) comes handy here.
In all target around 1000 tough questions during your quant prep which will require around 30-50 hours of preparation.
GMAT-GRE overlap: Probability (around 5 hours should be dedicated to probability).
Tough areas for GRE:
- Combinations & Probability (the word problems are very confusing).
- Standard Deviation.
- Harder Data Sufficiency for Integer Properties questions.
- Mixtures.
- Remainders.
- Triple venn diagrams.
- Converting from miles/km/hours/minutes, etc. to solve word problems.
Learn all the fundamentals and shortcut for solving question. Making sure you know the statistics and probability kinda helps you score 165+, Some people skip those parts & thinks that only 1-2 questions will come from these areas, but often it turns out that even 5-6 questions are asked & the target of achieving 165+ score becomes unachievable.
