To the Student: WHAT TO BRING ABOUT THE EXAM

MATH 8A Mathematics, Grade 8, First Semester

#10127 (v.3.0)

To the Student: After your registration is complete and your proctor has been approved, you may take the Credit by Examination for Mathematics, Grade 8, first semester.

WHAT TO BRING ? several sharpened No.2 pencils ? lined notebook paper ? graph paper ? straight edge ? graphing calculator

ABOUT THE EXAM The examination for the first semester of Grade 8 mathematics consists of 40 questions, of which 35 are multiple choice and the rest are short answer. The exam is based on the Texas Essential Knowledge and Skills (TEKS) for this subject. The full list of TEKS is included in this document (it is also available online at the Texas Education Agency website, ). The TEKS outline specific topics covered in the exam, as well as more general areas of knowledge and levels of critical thinking. Use the TEKS to focus your study in preparation for the exam.

The examination will take place under supervision, and the recommended time limit is three hours. A formula chart will be provided for you. You will be allowed to use a graphing calculator. You may not use any notes or books. A percentage score from the examination will be reported to the official at your school.

In preparation for the examination, review the TEKS for this subject. All TEKS are assessed. A list of review topics is included in this document to focus your studies. It is important to prepare adequately. Since questions are not taken from any one source, you can prepare by reviewing any of the state-adopted textbooks that are used at your school. The textbook used with our MATH 8A course is:

Randall et al. (2008). Prentice Hall Texas Mathematics, Course 3. Boston, MA.: Pearson Prentice Hall. ISBN 0-13-134019-0

The practice exam included in this document will give you a model of the types of questions that will be asked on your examination. It is not a duplicate of the actual examination. It is provided to illustrate the format of the exam, not to serve as a complete review sheet.

Good luck on your examination!
