This study guide aims to improve the math, mechanical, reading, aviation, nautical, and spatial apperception skills of candidates preparing for the Aviation Selection Test Battery (ASTB). It gives a clear breakdown on the types of questions you will expect to see in the test, and you will learn invaluable tips, shortcuts, and strategies to work quickly and confidently. The Officer Aptitude Rating (OAR) section in ASTB comprises the reading, math, and mechanical sections, which are identical to the Selection Instrument for Flight Training (SIFT) test battery. Typically, you only have 3 chances to get the minimum score of 50 (out of 80) in OAR to be considered for all careers offered by the U.S. Navy. All questions are multiple choice. The math test can be challenging. A calculator is not permitted and it is adaptive, which means the questions may become progressively harder depending on your performance in the earlier questions. The reading test is also adaptive and the questions can be intense. This book provides a concise explanation of key math concepts and formulas so that you can get up to speed quickly. More importantly, it describes powerful shortcuts to solve math problems in the shortest amount of time. The book also contains essential summary notes and 12 practice tests on mechanical, reading comprehension, aviation-nautical information, spatial apperception, and math with different levels of difficulty. Many examples and exercises covered in the book are frequently tested and there is an extensive set of over 750 worked examples and exercises to help you excel in the test.

GRE math problems tend to be very deceptive. The test folks know what methods students will choose when solving these problems and they may sidetrack students to do unnecessary work. They also know all about the common mistakes made by students, and their questions and choices are designed to expose these weaknesses. This study guide aims to improve the math skills of students taking the GRE. According to the official percentiles from ETS, more students achieve a higher percentile for verbal than quantitative. Many guidebooks focus on pages and pages of mechanical drills that may not be relevant. This book keeps to the scope of the test and is packed with invaluable insights, essential tips, and powerful shortcuts to solve GRE math problems quickly. Additionally, it explains key concepts and formulas so that the foundational principles are clearly understood and you can get up to speed within a short time. The book contains 300 problems, 250 worked examples, 250 exercises, and a 300-word list compiled from official tests. The problems are split into ten practice tests. The first four tests comprise 25 problems each, the next four tests comprise 30 problems, and the final two tests 40 problems. You should spend 40 minutes on each test and progressively improve your speed in solving the problems. If you can solve most of the problems in the final two tests, you are ready for the real GRE. A graphical analysis of GRE scores and percentiles, some advice on analytical writing, and a comparison with GMAT are also included.

This study guide aims to improve the English, math, reading, and science skills of students taking the ACT. It gives a clear breakdown on the questions you will expect to see in the test, and you will learn strategies to work quickly and confidently. Many students, including students with good GPAs, run out of time when doing the actual test. To do well in the ACT, you need to spot the different types of questions and pick the right strategy that keeps to the time limit. Ultimately, the test separates students who learn by memorization versus students who not only mastered the basics but are ready to adapt concepts and take advantage of multiple-choice questions. Unlike other guidebooks that focus on pages and pages of mechanical drills, this book is packed with many invaluable insights, essential tips, and powerful shortcuts to answer ACT questions quickly. Additionally, the book explains key concepts and formulas so that the student clearly understands the foundational principles and can get up to speed within a short time. Five reading, five English, and six science passages, as well as three 60-question math practice tests, a 300-word list from official tests, and an essay topic with six samples are provided. A graphical analysis of the ACT scores and percentiles, a correlation between the number of mistakes made and the expected score, some advice on university application, and a comparison with SAT are also included.

This study guide aims to improve the math skills of students taking the SAT. It gives a clear breakdown on the types of questions you will expect to see in the test, and you will learn strategies to work quickly and confidently. The test comprises two math sections, in addition to the reading and writing sections. Most students know how to work out the answers. Yet, many of them, including students with good GPAs, run out of time when doing the actual test. This is compounded by restrictions on the use of calculators and free-response questions that require the student to input the answers. There are often several ways to get the answer to the same problem. To do well in SAT math, you need to spot the different categories of questions and pick the right strategy that stays within the time limit. The test separates students who learn by memorization versus students who not only mastered the basics but are flexible in adapting concepts. Unlike other guidebooks that focus on pages and pages of mechanical drills, this book keeps within the scope of the test and is packed with invaluable insights and powerful math shortcuts. Additionally, the book explains key concepts and formulas clearly so that the student understands the foundational principles and can get up to speed quickly. Essential tips for reading, grammar, and essay writing are provided, together with a 300-word list from official tests, a graphical analysis of SAT scores and percentiles, a correlation between the scores and the number of mistakes made, some advice on university application, and a detailed comparison with ACT.
