GRE exams for those seeking a Masters in Computer Science Since the Computer Science GRE exam was dropped, I have to take the normal GRE exam (sighs).  I've looked at a few sample questions, and it's something I'm just not good at.  I have a Bachelors in Computer Science with a 3.1 GPA (out of 4.0)  I have two core questions:


How well do I have to do to get accepted into most decent universities for a Masters in Computer Science?
What is the best way to study and practice for GRE exams for a C.S. major?


UPDATE (02/18/2015): 

I got my scores in for GRE. Verbal: 153, Quantitative: 160, Essays: 4.0. I'm not sure how good this is or not yet.

I studied for about 4 months. First 2 months it was little studying every week. The third month was studying every other everyday. The first 2 weeks of the 4th month studying everyday. The last 2 weeks were heavy studying.
How well do you have to do on the GRE?  That depends entirely on how much weight the admissions committee gives to GRE scores.  Some universities may not really care.  Others may use GRE's as part of the screening process.  Universities have not adopted a universal policy as to how GRE scores should figure into admission decisions.
It doesn't matter if you are a CS major or any other major -- general principles of good study techniques for the GRE hold true for everybody.  If you are an independent learning who is self-motivated and skilled at structuring your own study, then you can probably just get some good test prep books.  If you need more structure, then you might benefit from paying for a course.
