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, and you can’t do the worksheets without having first read the Course Notes:
Make notes from the worksheets on how each command works. What do the options used in the worksheets mean, for each command? (See the weekly Command List.)
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.

Worksheets prepare you for the upcoming assignments.
This course has two midterm tests (10%, 15%) and one final exam (40%).
Note that your upcoming Midterm Test #2 is worth approximately five assignments put together. Don’t spend all your time doing an assignment at the expense of studying the Practice Tests and Answers for the Midterm Test.
Your Second Midterm test is 45 minutes long and contains approximately 45 multiple-choice questions similar to those found in the two preceding Practice Tests and Answers. Do both practice tests before the Second Midterm test! You must write the test in the lecture class in which you are registered.
Do both the practice tests before the Midterm test!

to separate multiple commands on the same line, to save space and paper, e.g. three separate commands can be written on one line like this: date ; echo "hi" ; ls
vim
or nano
.For full marks, you must read and understand the Test Instructions.
Blackboard has some quizzes taken randomly from the second practice test in Practice Tests and Answers. Do both the first and second practice tests and quizzes to prepare for Midterm #2.
The practice test itself is not part of your course grade, but these quizzes are part of your course grade.
See the Blackboard Quizzes section located in Practice Tests and Answers.
The Final Exam is 110 minutes long and contains approximately 110 multiple-choice questions similar to those found in the three preceding Practice Tests and Answers. Do all three practice tests before the Final Exam!
All three practice tests will be posted under Practice Tests and Answers. The Final Exam is comprehensive of the whole course; you need to do all three practice tests for the Final Exam.
I spent many hours correcting your errors and omissions on your mark-sense forms. Many of you lost marks for that. Before your final exam, carefully re-read the posted Test Instructions. Penalties go up for making the same errors on subsequent tests.
Here are some statistics for the second midterm test:
150 students are currently registered in the course. (We started the term with 240 students in early September.)
Of the 150, 10 did not write the test, leaving 140 who did.
Of the 140, 19 did not enter a valid test version code on the Scantron form. (I had to enter all those test version codes for you, so that you could get some marks.)
Of the 140, 13 did not enter their own name to match the name on file with the Algonquin Registrar office. (These students didn’t check their names using the Name Game before the test.)
Of the 140, 7 did not enter their own student number correctly.
Of the 140, 3 did not enter their own name or their own student number correctly, so the test couldn’t be marked. (I had to fix those names for you so that you could get some marks.)
Of the 140, 4 did not put their full name on their question sheet. (2 left the name field blank. I had to fix those for you, so that you could get your question sheet back for the bonus assignment.)
Of the 140, 58 answered question #45 even though the Test Instructions printed at the start of the test told you to leave the question blank (no answer).

One student got 100% on the test, but lost marks for failing to write their name on the question sheet.
Take notes in class! Keep a pad open on your desk.

Many students find that hiring a personal tutor helps them get through the first term. Financial assistance is available. See the Tutoring heading in the Course Introduction.
You are not paranoid if they really are out to get you! See the Week 03 Notes HTML for command pipelines to count the SSH attacks on the CLS.
