When you combine Multiple Attempts with Numerical Simulation, you can create a test that changes the values of a question every time a candidate starts a new attempt. This ensures that the candidate must solve the problem again rather than relying on their previous result. Even though the numbers change, Inspera still marks the answer automatically based on the formula you provide.

How it works

In a math question, you can set a variable (X) to generate a random number for each attempt.

Imagine a math question: "What is X + 5?" 

Instead of a fixed number, you set X as a random variable between 1 and 9. 

• Attempt 1: The system gives the candidate 9. (Problem: 9 + 5) 
• Attempt 2: The system gives the candidate 3. (Problem: 3 + 5) 
• Attempt 3: The system gives the candidate 5. (Problem: 5 + 5)

Example

In this example, we have the following variables:

• Group_1: Generates a random number between 1 and 9, with a step size of 1.
• Group_2: The candidate input

Candidate experience

The candidate will see a different value for the question variable (ta1) in each session:

1. Attempt 1: Variable generates a value of 9.0.

   

2. Attempt 2: Variable generates a value of 3.0.

   

3. Attempt 3: Variable generates a value of 5.0.

   

Correct answer

Despite the changing variables, the system automatically evaluates the response against the defined formula. In the View Submissions page, the question is marked as Correct as long as the candidate provides the right answer for the specific numbers generated in that attempt.
