+=== 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
+<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>.
