It's good practice, 3/5 stars for not being overly frustrating. Don't buy these for the quantitative overview, there are a lot better resources to use (TTP or any of the long list from the GMAT reddit page). These questions are definitely harder than the ones in the 2024-2025 Official Guide with Quant, DI, and Verbal questions. However, there are only 203 questions in this book, and they could have certainly made more. I would definitely do these problems though, even if you find other ways of accessing them without buying the book.
Unrelated to this book: In my Goodreads challenge roundup for 2024, they had a special section showing the first book I reviewed in 2024, which then created this strange pressure to have an outstanding book as my first review of the year. I have at least five Chinese audiobooks going that I would love to review, but my pace has been so slow that I don’t think I’ll be able to finish any of them anytime soon. But instead, we're going to do four Goodreads reviews on the GMAT test prep books because something needs to pad out my book goal for this year, and I have "read" this book.
