We are professional GRE tutors based in San Diego, California. Combined, we have over 25 years experience teaching and tutoring students for this exam.  \nWhy did we write this guide? We wrote this guide because, like most experienced GRE tutors, we believe in using real GRE questions whenever possible. However, although ETS (the maker of the GRE) provides two free computer-based practice GREs, it does not provide any answer explanations for the PowerPrep CAT (computer adaptive test) questions! Even the answer explanations that ETS does provide in the Official Guides are often noticeably lacking and/or difficult to comprehend for the average student.  \nThe explanations within this book are meant not only to make the answers clear, but also to help you build (slowly, and over time) the type of critical thinking, reading, vocabulary and mathematics skills that you will need to succeed on the GRE. In our explanations, we aim to be clear, concise, direct, and simple, and we always welcome suggestions for improvements.  \nPlease also read Brian’s detailed Guide to Navigating the GRE Powerprep Online Practice Tests.  \nGood luck with your GRE prep, and please contact us with any comments or questions!  \n—Vince Kotchian and Brian McElroy, professional GRE tutors, San Diego CA  \nVince Kotchian:  \n[Email: vince@vincekotchian.com](Email: vince@vincekotchian.com)  \n[Phone: 760.542.8395](Phone: 760.542.8395)  \n[Web: www.vincekotchian.com](Web: www.vincekotchian.com)  \nBrian McElroy:  \n[Email: mcelroy@post.harvard.edu](Email: mcelroy@post.harvard.edu)  \n[Phone: 866.584.8886](Phone: 866.584.8886)  \n[Web: www.mcelroytutoring.com](Web: www.mcelroytutoring.com)  \nIntroduction  \nWhen preparing for the GRE, one must remember to use official materials (materials written by ETS, the maker of the GRE) whenever possible. Third-party strategy and learning guides certainly have a place in the GRE prep process, but far too many students waste their GRE preparation time by using non-official test questions from companies such as Kaplan, which are often far different than the real thing--particularly with regard to GRE Verbal Questions, where it is difficult, if not impossible, for 3rd-party questions to fully replicate the wording, tendencies, and “feel” of official ETS questions.  \nHere are al l of the GRE official materials","cbCaia2NEGHEWrme","https://ap.wps.com/l/cbCaia2NEGHEWrme","pdf",13343148,316,"English","# PowerPrep Test 1\n## Verbal Reasoning\n## Quantitative Reasoning\n# Powerprep Test 2\n## Verbal Reasoning\n## Quantitative Reasoning","[{\"question\":\"What does this book explain?\",\"answer\":\"It provides detailed explanations for all 320 questions from ETS’ free PowerPrep Online practice tests, including both Verbal and Quantitative sections.\"},{\"question\":\"Why are answer explanations included here?\",\"answer\":\"ETS provides practice tests but does not supply adequate answer explanations for the PowerPrep CAT questions, so the guide aims to make answers clear and build needed test skills over time.\"},{\"question\":\"Which GRE materials does the introduction recommend?\",\"answer\":\"It recommends prioritizing official ETS materials such as PowerPrep Online, Powerprep Plus Online, official paper-based practice tests, and the Official Guide to the GRE General Test and related official practice question books.\"}]","Vince & Brian’s GRE PowerPrep Explanations - Online Explanations | PDF",1790510842,796]
