GRE Quant - (163 out of 170)
* This guide is only for the Quant Section of the General GRE test
* This guide is particularly suitable for those who already have a good background in mathematics - engineering/science majors, for example.
* All of the resources (books/software) mentioned in this guide can be downloaded for free.
* In case anyone is wondering, my GRE Quant is 163.
* Also read other guides, and see which one suits you the best.
* Based on my experience applying to the Engineering programs in the US, a Quant score of 160 is good, 165 is excellent and 167 is extraordinary. You can also shoot for a perfect 170, but I don't think it would make much of a difference towards your chances of being admitted. After you cross 165, each increment starts to mean less and less.
* You can check the average GRE scores for mechanical engineering, electrical engineering, and computer engineering at [A], [B] and [C], respectively. But take these scores with a grain of salt - they are 'average scores' after all.
Note: [A] and [B] do not mention whether the scores are for MS or Ph.D., though I *think* they are for MS (since [C] is for MS).
Guide (based on how I prepared):
A - Take two or three untimed paper-based practice tests from  in order to identify the topics you are weak at. I would recommend not taking a computerized test at this stage. You should save them for later.
B - Once you have identified the topics you are weak at, study them thoroughly using  and . Furthermore, solve as many practice questions as you can from .
C - Take one or two timed paper-based tests from . See how you perform on the sections you identified as weak earlier. In addition, take note of the topics that you believe require improved time-management.
D - Based on the results of step 3, study the relevant topics from . In addition to , you can use youtube videos to learn tricks/strategies to improve your time-management skills. Furthermore, solve as many questions from  as you can
E - It's time to take the PowerPrep Test 1. I would recommend saving the second test for later.
F - Take other mock tests
G - Take the second PowerPrep test. While taking this test, and, of course, the tests mentioned above, keep an eye out for the topics that give you a tough time, and study them thoroughly from an authentic GRE prep book/online resource.
