Thanks for choosing Manhattan Prep. As part of our commitment to providing the best GRE preparation materials, we are constantly reevaluating how accurately our practice problems reflect the real GRE. As you mentioned above, we have noticed that our Text Completion and Sentence Equivalence GRE Strategy Guide did not cover the full breadth of questions students might experience on the exam. In response to this discovery we are releasing these two free supplements to that book, which contain a total of 60 new practice questions. These questions, in combination with the drill sets found in our strategy guide, cover every type of Text Completion and Sentence Equivalence problem you might experience on test day, from those with very difficult vocabulary, to those based around complicated sentence structure. These supplements are available for download in our student center for anyone with our Text Completion & Sentence Equivalence book. If you have any questions about this, please let me know.
