Logic Based Reasoning Comprehension section is garbage (warning!)
Reviewed in the United States on July 7, 2020
I'll tell you the worst part of the book: Logic Based Reading Comprehension. It is full of garbage questions and equally useless explanations, which is ironic since that is the "logic" section of the Verbal test. Nothing is logical about that section. Other people also seem to share the same opinion as I do.
The math sections are the best part since it's very comprehensive and leaves no stone unturned. There are some abnormally difficult math questions, it prepares you mentally for the few tough questions on the real GRE.
The Vocabulary and Reading Comprehension sections are pretty good comprehensive too. In general, these sections are very grindy since you need to memorize a lot of words and hack through the flowery language of the reading paragraphs. It's good training for the real thing. But I would still recommend doing the Verbal sections from the official GRE book and old GRE tests (freely available on the internet).
