i always have a feeling that old QR is easier than SAT, which includes lots of word problems. now i am just wondering how they differ in terms of difficulty and types of questions
To be honest, I really don't remember the SAT math all that well anymore - but I think the QR is very very similar just with significantly less time. Most of the individual questions on the QR are not very difficult - it's all about doing all of them in the time allowed.
Would the QR sections from a GRE prep book help in addition to Destroyer/Topscore/Achiever? or would it be best to just get an SAT prep book and use that for RC and QR?
