How to create a quiz form which shows if an answer is correct?

Can I specify a correct answer? For a quiz for instance, I'd like to let the user know if their answer is correct or incorrect.

It is possible to show the results to the user after submission using quizform.jotform.io. Please see the screenshot below. Refer Turn-Your-Form-into-a-Quiz-or-Exam-

Do try this and let us know how this works for you.

Thanks.

Thank you for your response.
I have tried that and it works great but only with a few types of fields. I
would like to show a correct answer using the passage test widget.
Is there any workaround for this?

Unfortunately there is no workaround to achieve your requirement. Please note that only following question can be used in quiz form:

Radio Button

Checkbox

Dropdown 

Input Fields

Ok. Is there a way to put an input field in the middle of a sentence?

Yes, you can use the Short Entry field or any other field but in that case, you have to design the Quiz Form yourself. Please check this workaround:

In the demo form, we used the Single Choice field, Short Text Entry field, Text field, and the Form Calculation widget.

The Score text field will update automatically based on the selected answer in the Question field. If yes, then the score is "1". If no, then the score is "0". You may also assign a value for each option, here's a guide: How-to-Assign-Calculation-Value.

The Form Calculation widget will add the total score using the values from the Score fields.

You can separate the page using the "Page Break" tool. In this way, the user will not see the result immediately.

If you want to hide a field, just right click it and then select the "Hide" option. You may need to do this in the Score field and Total (Form Calculation widget) field.

Here's the result:
