CDLS Credit Recovery (CR) courses are designed for students who have taken a course and failed it. 

 

CR courses are organized so that students can take a pre-test for each lesson/unit. The exemption of activities is based on which content in the pre-test that the student demonstrates mastery in, not the overall "grade" on the pre-test. 

Life Science deals with the study of all types of living organisms, such as microorganisms, plants, animals, and humans. The field focuses on their organization and life processes. Life Science A begins with the basic unit of life—the cell. You’ll discover how cells build up tissues, organs, and systems. You will study the growth and development processes of different organisms and see how genes are responsible for the traits of organisms. You’ll also explore natural selection and artificial selection and their effects on the genetic traits of organisms.
