Reminder: There are now two quizzes that you need to complete on Blackboard as part of your term Quiz mark. A third quiz will be posted before the Final Exam. The Quizzes are not optional.
Check the due date for each assignment and put a reminder in your agenda, calendar, and digital assistant.
Form a small study group to do the worksheets. Each person tries the example given, and you make sure you all get the same answers. Worksheets teach you how commands work. Worksheets are not for hand-in; they are not worth marks.
The worksheets are available in four formats: Open Office (ODT), PDF, HTML, and Text. Only the Open Office format allows you “fill in the blanks” in the worksheet. The PDF format looks good but doesn’t allow you to type into the blanks in the worksheet. The HTML format is crude but useful for quick for viewing online.
Do NOT open the ODT files using any Microsoft products; they will mangle the format and mis-number the questions. Use the free Libre Office or Open Office programs to open these ODT documents. On campus, you can download Libre Office here.

Students with errors on their forms need to re-read the Test Instructions, get their own midterm test question sheet from their lab instructor (Wenjuan has all the Section 020 question sheets), then follow the posted instructions for Booking an Office Apppointment with Ian to fix their mark-sense forms. Ian will also carry the Section 010 question sheets and all the mark-sense forms to all his lab periods in Week 10; see him in any of his four scheduled lab periods.
