I just took the GRE today and would like to offer some words of encouragement to those testing in the near future: don’t be too scared by the Verbal practice sections in Achievable. The passages and questions on the actual test were a bit less challenging than those in the ten practice exam sections. I was scoring in the high 150s to mid 160s on nearly all of the practice sets but managed a 170 on the GRE without too much trouble (plenty of extra time).
Pay attention to spoilers in answer choices and look for cite-able sentences in the passages. It does work. The Quant sections were a different story, to my chagrin.
