SCI 6A Science, Grade 6, First Semester

#PR-56809, BK-56810 (v.4.0)

To the Student: After your registration is complete and your proctor has been approved, you may take the Credit by Examination for SCI 6A.

WHAT TO BRING ? several sharpened No. 2 pencils

ABOUT THE EXAM The examination for the first semester of 6th grade Science consists of 34-36 questions, of which 28-30 are multiple choice and the rest are short answer and essay. 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. 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 SCI 6A course is:

? Texas Science Fusion, Student Edition. Houghton Miller Harcourt Publishing. ISBN 978-0-544-06779-7 (digital)

? Texas Science Fusion, Write-in Student Edition. Houghton Miller Harcourt Publishing. ISBN 978-0-544-02552-3 (print)

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!
