PDF copies of each unit are available for download but note links to practice questions etc. will not be included so recommend using the online lessons. If you download the pdfs you'll need to access the "Science 20 CD" link in "Student Resources" to access answers to practice questions, multimedia segments etc. Also note the online lessons are updated on a continuous basis while the pdf versions are updated on an annual basis so again, best to use the online lessons.
