Hello All! I wanted to ask how difficult is the GRE Quant portion? I have the Cracking the GRE 2016 edition and Ii understand the lessons and how to do the problem in the examples but when i finish the chapter nd try the practice test it doesn't match anything that its teaching the subjects. The question is totally different from what they're teaching me so I wanted to know are the math questions really as difficult as the practice test are making it out to be?
