    GENERAL DIRECTIONS
     • You may work on only one module at a time.
     • If you finish a module before time is called, check your work on that module only.
       You may NOT turn to any other module.
    TIMING
        Reading and Writing, Module 1: 39 minutes
        Reading and Writing, Module 2: 39 minutes
          10-minute break
        Math, Module 1: 43 minutes
        Math, Module 2: 43 minutes
        The above are standard times. If you are approved for accommodations involving
        additional time, you should give yourself that time when you practice.
