The GRE features the same quantitative content, just in different question and test format.

My clients average a 9 point improvement on quant and verbal EACH

For verbal, I prefer that clients use the Magoosh GRE vocabulary app on their smartphones to memorize vocabulary, and then we focus intensively on Logic-based Reading Comprehension

I supplement with practice problems from the ETS Official Guide, and I like to use practice test from ETS or the GRE Prep club website
