This is the book you are looking for.
Format: Paperback, Format: Paperback
After searching through about four different vocab books, I finally found one I can truly vouch for: Robert's Extremely Nerdy Guide to Digital SAT Vocabulary.
Robert is actually my daughter’s SAT tutor and recommended this book. At the time, my daughter had almost given up on the vocab portion of the SAT—there were only 7 weeks left to the test date (we’re now down to just 2 weeks). Honestly, what can you achieve in that short time? Still, I decided to buy it—what did we have to lose?
Because I’d already gone through so many SAT vocab books, I knew a good one when I saw it. Just flipping through the first few pages convinced me this was the right fit, and my daughter immediately got to work. The book starts with 6 sections on word roots, then moves into 26 sections of similar-meaning words. Each chapter includes a matching activity (which my daughter finds essential for retention) and ends with SAT-style practice questions.
Since using this book, she spends much more time memorizing and testing words. I only wish we had discovered it earlier so she could have had more time to digest and apply what she’s learning. Before this, she was getting about 50% of vocab questions right on a good day; now, after just over a month with this book, she’s averaging 80–90%.
As a side note, I’m not a native English speaker, and I’ve also learned so many words by reviewing her answers. Almost every word I’ve come across in the past and thought, “I should look this up someday” seems to be in this book—a testament to why the SAT brought vocabulary back for the digital test.
This book has served my family extremely well, and I plan to start my youngest child on it earlier. Get this book, and start early.

Fantastic categories for SAT vocab
Robert’s vocab book has been a fantastic addition to my tutoring resources. My students love the ease of progression through the short chapters. It is helping tremendously with vocabulary comprehension in addition to his mock tests.

Great list of words
Format: Kindle
Useful words, well organized. It's a valuable resource for students who are looking for points beyond grammar/notes/transitions.

Robert has always been a trusted author in the field of SAT, but I can’t express how helpful this book is for the test and for college.
