1.2 Assignments and lab work this weekIndexup to index

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.

1.3 WorksheetsIndexup to index

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:

  1. Read the web notes. (Please: Read All The Words)
  2. Do the relevant Worksheet(s).
  3. Do the relevant Assignment(s).

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 List of Commands.)

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 get a copy here: Course Introduction: Install Libre Office.

Worksheet #06 is for the optional VIM Bonus Assignment (extra credit):

Worksheet #08 is for Assignment #09 HTML.

Worksheets prepare you for the upcoming assignments.

Note that your upcoming Midterm Test #2 is worth more than 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.

1.4.1 Midterm Test #2 – Wednesday March 21 (week 9) – 15%Indexup to index

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.

  • Time: in your one-hour lecture class on Wednesday in Week 9 (March 21).
  • General seating; sit anywhere.
  • 45 minutes for 45 multiple-choice questions
  • Do both the practice tests before the Midterm test!

  • The tests and exams are all closed-book, no aids, just like your job interview. You will be given some scrap paper to write on.
  • For full marks, you must read the Test Instructions before the test for important directions on how to enter your name, student number, answers, your lab (not lecture) section number, and the test version code on the question sheet and the mark-sense forms.
  • There may be more questions on the test than you can answer in the time allowed; answer the ones you know, first.
  • A set of practice questions and answers for the second midterm test is posted in Practice Tests and Answers.
    • The tests use the semicolon ; 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
    • Do not use semicolons as an interactive human user! Type each command on its own line with the [Enter] key.

  • Weekly web pages (in the notes) up to and including Symbolic Links.

  • 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.

1.4.4 The Final Exam – 10:30am Saturday April 28 2018 – 40%Indexup to index

Final Exam: Saturday April 28 10h30am (10:30am to 1:30pm; 3 hours – 40%) in room T102A,B,C.

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.

2 Midterm Test #2 AnalysisIndexup to index

I spent an hour 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:

The 90 class scores:

100 98 95.5 95.5 93.5 93.5 93.2 90.9 88.6 86.4 86 84.3 83.2 80.2 80.2 80.2 79.5 78.3 78 78 78 78 77.3 75.7 75.7 75.7 75.7 75 75 75 75 75 73.5 72.7 71.3 70.6 70.5 69.8 69.8 69 64.8 64.2 63.7 62.4 61.7 60.1 60.1 59.9 57.9 57.9 56.8 56.2 55.7 55.7 53.5 53.5 52.9 52.3 51.2 50 49 49 48.5 47.7 47.7 47.7 47.7 44.5 43.2 42.3 42.3 40.9 40.1 38.6 37.9 37.9 36.4 35.6 34.6 34.1 34.1 33.4 33.4 28.7 28.1 25.7 20.5 20.5 19.4 10.5

One student got 100% on the test, but lost marks for answering Question 45.
