=== Grading ===

All students have to:
  * pass two tests:
    * one on the topics tagged with [shell]; this test will take place after the corresponding classes
    * another on the topics tagged with [programming]; this test will take place on the last lab classes
  * complete two assignments:
    * write a shell script - [[os_cp:2025:shell_assignment|list of topics]]
    * write a concurrent program - [[os_cp:2025:prog_assignment|programming assignment details]]
<html><div style="margin-top:-1.2em"></div></html>
__Absence__, including an excused absence, for more than one-third of the classes,
__results in failing__ the course.

The tests will be written on the lab computers, on a dedicated virtual machine.
You may (and to answer some of the questions, you must) use the terminal.
You are free to use any software available on the machines (e.g., the ''man'' command).
You must not use the Internet or bring any materials to the test.
You may make yourself familiar with the test framework at
<html><a href="/jkonczak/test-en/" class="wikilink1">this example test</a></html>.
