# Randomquestionpool

With the help of \randomquestionpool it is possible to select from a multitude of questions always exactly the same
number for each student.

You use \randomquestionpool to define question groups. A question for the student is selected from each group.
Each question can be of different types. The system randomly selects a question from each group.

Each group is defined by the indices of the questions.

1\randomquestionpool{start}{end} --> \randomquestionpool{2}{5} 

Here, questions 2, 3, 4 and 5 are grouped together.
The student will see either the 2nd, 3rd, 4th or 5th question.

A similar functionality is offered by \randomquickcheckpool. For examples, see Quickchecks.

# Example

Here you can see an example of 4 different questions.
Two question pools are formed.

The first pool contains questions 1 and 2.
The second pool contains questions 3 and 4.

The student sees either the 1st or 2nd question as question 1 and either the 3rd and 4th question as question 2.

Question 1 and question 7 in the code would not be displayed by the system.
If \randomquestionpool is specified, then only questions that are within the indexes are included.
