1 263 Physics A Examination for Acceleration (EA)/Credit by Exam (CBE) The exam you are interested in taking is designed to test your proficiency in the relevant subject matter. You should be thoroughly familiar with the subject matter before you attempt to take the exam. This can help you prepare for the exam by giving you an idea of what you need to review. You can check your familiarity level by reviewing the Texas Essential Knowledge and Skills (TEKS) for this course (see below). To refine your skills, you can refer to any of the state-adopted textbooks. Texas Essential Knowledge and Skills (TEKS) Every question that appears on this exam is derived from the knowledge and skills statements and student expectations within the Texas-mandated standards, the Texas Essential Knowledge and Skills (TEKS). You can view the TEKS for this exam online via the following link: Refer to section (c), Knowledge and skills, A 8D. Throughout this guide, you ll see TEKS references. These refer to the numbers listed under (c) Knowledge and skills; for example, A or 3B. Note: Coverage of the TEKS is split between Physics A and B; so those TEKS not covered in this exam are covered in the Physics B. Materials Needed You will need to bring a #2 pencil to complete the exam. You are also allowed to bring and use a graphing calculator. You will receive a computer-graded answer sheet when you arrive at the testing center. You will be provided a formula sheet with your exam. The formula sheet is also included at the end of this for your review. Exam Structure You will be allowed 3 hours to complete this exam. The exam consists of 50 multiple-choice questions worth 2 points each for a total of 00 points. The exam consists of the following 3 parts: Part : Science Processes and Methods (0 questions) Part 2: Motion (20 questions) Part 3: Forces (20 questions) K-6 Education Center

2 PHY A & Scholastic Honesty When you arrive at the testing center, you will be asked to carefully read the exam rules and sign a statement agreeing to take the exam in accordance with the rules. This is called the Examinee s Certification. The following is a copy of these rules: Examinee s Certification This certification must be signed before the exam is administered and then returned with the completed examination attached, or credit for the exam will not be given. Scholastic dishonesty is a serious academic violation that will not be tolerated. Scholastic dishonesty encompasses, but is not limited to: copying from another student s work; using an unauthorized testing proctor or taking the exam at an unauthorized testing location; using materials not authorized by a testing proctor; possessing materials that are not authorized by a testing proctor, such as lessons, books, or notes; knowingly using or soliciting, in whole or part, the contents of an unadministered test; collaborating with or seeking aid from another student without authorization during the test; substituting for another person, or permitting another person to substitute for oneself, in taking a course test or completing any course-related assignment; using, buying, stealing, or transporting some or all of the contents of an unadministered test, test rubric, homework answer, or computer program. Evidence of scholastic dishonesty will result in a grade of F on the examination and an F in the course (if applicable). At the testing center, you will be asked to sign a statement that says you have read the above and agree to complete the examination with scholastic honesty. K-6 Education Center 2
