Counting radiobutton aswers

Questions
1

I’m using radiobuttons for a multiple choice quiz. If I have 10 radiobuttons, what is the easiest way to count the number of correct answers when the student submits?

To keep the quiz secure, you definitely want to handle the scoring on the backend. If you store correct answers on the page (even in hidden variables/groups), users can inspect the page source and cheat easily.

YoU can use a Backend Workflow to compare submissions against the database securely:

1. Database Structure Create a Question data type with correct answer:

  • QuestionID (number)

  • CorrectAnswer (text)

2. The Backend Workflow Go to Backend Workflows and create an API workflow named gradeQuiz.

  • Parameters: Add text parameters for every Question and selected answer (`Q1` ans1, `Q2` ans2 and so one) and a student parameter (User type).

  • Action: Create a new thing (QuizResult).

  • Field 1: Student = student (parameter).

  • Field 2 (The Calculation): Set a number field Score to calculate the total immediately. You can sum them up using the :formatted as number operator, which turns a “yes” into 1 and “no” into 0 , Do a search with Quesiton and user anser if it return the question that mean the answer is correct , else its not.

3. The Trigger On your quiz page’s “Submit” button workflow:

  • Use the action Schedule an API workflow.

  • Select gradeQuiz.

  • Map the parameters to your page inputs ( Q1 = your question and ans1 = Radio Button A's value ans1 = Radio Button A's value, etc.).

  • Send Current User for the student parameter.

4. Displaying Results Once the workflow is scheduled, navigate the user to a results page. You can display the score by searching for the latest result: Do a search for QuizResults (Constraint: Created By = Current User, Sort: Created Date Descending):first item's Score

Thanks Baloshi. That seems extremely complicated, it could be done in a simple workflow adding up the right answers.
