# What is Wiris Quizzes?

#### Wiris Quizzes 4 documentation

This documentation page has been updated to the latest Wiris Quizzes version. You can find the same information for the previous versions here.## Automatic assessment

As a teacher, interpreting the student’s answer mathematically is natural or almost involuntary when we grade exams by hand, but a typical problem for computers is that they can only understand text literally. In this example, the correct answer set by the teacher is . Another equivalent way of writing this will also be correct, for example, by distributing the product: .

## Random parameters

Another notable feature of Wiris Quizzes is its ability to generate random questions. This means we can write a general question with different data each time the question is opened. Considering the previous example, in the animation below we'll make part of the question random.

In Wiris Quizzes, you can define and manage random variables. We do this in the Wiris Quizzes Studio Interface. In fact, this is where most of the work is done in Wiris Quizzes. It's here we define a random length and the other side of the triangle correspondingly. Then we modify the correct answer using the new variable as part of the formula.

Finally, we insert these variables into the question statement. Now if two different students view the question, we can confirm the values have changed. Since the values change, naturally the solution is also different for each case.

## Units of measurement

Wiris Quizzes is great for creating mathematical questions, but because it understands units of measurement it's also appropriate for physics, chemistry, biology, economics, and more.

Thus you can create a question which answer includes units and you can even penalize answers without units or without the specified units.

## Student's answer

Another interesting feature of Wiris Quizzes is using the student's answer in the question feedback. This way it's possible to show the student why he has answered wrong or which steps he should have followed. We can add feedback, for instance, to a question asking for a particular function to show the difference between the plotters of the answered function and the correct one.

## Training

It may seem like creating a question with Wiris Quizzes isn't easy, and that may seem worse if you consider you won't be used to its user interface. To help ease the transition, we are offering free Wiris Quizzes Training. This course consists of three parts, which cover theoretical contents, examples, and exercises.
