For MCC based question, check the correct checkbox for multiple correct options.
+ * **Create Hook based Test Case**
+
+ Select Hook from Add Test Case field.
+
+ In Hook based test case type, moderator is provided with a evaluator function
+ called **check_answer** which is provided with a parameter called **user_answer**.
+
+ **user_answer** is the code of the student in string format.
+
+ A moderator can check the string for specific words in the user answer
+ and/or compile and execute the user answer (using standard python libraries) to
+ evaluate and hence return the mark fraction.
