Algebra 2A

Credit By Exam Review Sheet
This Credit By Exam Review Sheet can help you prepare for the exam by giving you an idea of
what you need to study, review, and learn. To succeed, you should be thoroughly familiar with
the subject matter before you attempt to take the exam.

Every question that appears on the Credit by Exam/Examination for Acceleration is grounded in
the knowledge and skills statements and student expectations within the state-mandated
standards, the Texas Essential Knowledge and Skills (TEKS). It should be noted that an exam
will not test every student expectation. However, it is important that students study and know
the entire scope of the TEKS so that they can develop a complete understanding of the content.
The CBE/EAs are a global exam grounded in the TEKS and are not designed to be a final exam
for the University of Texas high school courses. You can view the TEKS for this exam online at
Since questions are not taken from any one source, you can
prepare by reviewing any of the state-adopted textbooks.

About the exam
The Credit By Exam consists of 40 multiple-choice questions that are worth 1 point each. You
will be allowed 3 hours to take the exam and you will be allowed to use a graphing calculator.

Concepts and Objectives
The bulleted list and sample questions below may not refer to all the material that will be in the
exam. This list only provides additional information for some of the student expectations tested
in the Algebra 2 First Semester Credit by Exam. The use of problem-solving skills is important;
all problem-solving activities require more than one step. In addition, you may be asked to use
algebra and arithmetic skills from previous math courses. To prepare for this exam, refer to the
Texas Essential Knowledge and Skills for Algebra 1, Geometry, and Algebra 2.

Ultimately, you should use the TEKS to guide your exam preparation.
