For teachers and parents

  • Printing: open a worksheet and use the print button, or your browser's print command. The site navigation is left off the printed page.
  • The answer key always begins on a new page, so you can print only the first pages for students.
  • Set A and Set B cover the same unit with different questions — handy for a retry, or for two halves of a class. The mixed reviews may also revisit a question from a unit sheet.
  • Same questions as the site: every worksheet is drawn from the same bank as the practice questions and quizzes, so the explanations match.
