valkener Posted January 29, 2013 Posted January 29, 2013 The GRE often has quanitative comparison, which numbers do you use to plug in to check if A or B is bigger/smaller/equal/cannot be determined? So far I have come up with -1, 0, +1 and then depending on the problem another set of +/- integers.
iowaguy Posted January 29, 2013 Posted January 29, 2013 Be sure to plug in a fraction as well. I had a couple of problems on my official test this fall where fractions were the "trick" part of the comparison... Quant_Liz_Lemon 1
Loseric Posted January 30, 2013 Posted January 30, 2013 The fraction is a great suggestion - usually they're the trick. One of the prep books recommends trying the ZONE 1 formula: zero, one, negatives, extremely large/small.
Brent@GreenlightGRE Posted February 10, 2013 Posted February 10, 2013 You want to plug in numbers that represent a nice cross-section of all numbers (big, small, positive, negative) I recommend 0, 1, -1, 1/2, -1/2, 10 and -10 If you're interested, we have a free video on plugging in values: http://www.greenlighttestprep.com/module/gre-quantitative-comparison?id=1098 Cheers, Brent
