GED Test Social Studies Review

I teach GED prep in a correctional center and have had a hard time finding books exposing my students to questions similar to the actual GED test. This book is the closest I've come so to finding a book that accomplishes what I need. The problem is it the book says there are additional tests online, but those tests are just online versions of the tests in the book.

I’ve tried 3 different books but this one is the best of them, I recommend it for those who want to pass the exam
