Check the due date for each assignment and put a reminder in your agenda, calendar, and digital assistant. Just like in the Real World, not all due dates are on the same days or at the same times.

Worksheets are preparation for your assignments. You can’t do the assignments without having done the worksheets first.
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 are not for hand-in; they are not worth marks; the assignments test your knowledge of the lectures and worksheets.
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 Worksheet 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.

Read the Test Instructions (all the words) before your midterm tests. Put these dates into your phone!
Tests take place in class in your 50-minute lecture period, not in your lab period. Each midterm test is 45 minutes long and contains approximately 45 multiple-choice questions similar to those found in Practice Tests and Answers.
The Final Exam is three hours long. Take a washroom break before you start.
Your time as a student is valuable. See the Week 03 Notes HTML.
Keep a notebook with a List of Commands in it. - You need to write down yourself what each command does. - I will check for this list in your lab periods. - Check the updated list of commands each week.
The CLS will lock out your IP address if you can’t type your own userid correctly.
If this happens, you have to follow the posted directions to have me unlock your IP address. You can change to another IP address. You can always come to school where no IP addresses are locked out.
