Is there any plugin to publish exam result? [closed]

Do you want the long answer or the short answer? Okay fine I’ll give you both.

Short answer, no (at least not one that I know of that does this)

Long answer, no but you can do this pretty easily by using other plugins. Here are a few ways to go about it.

1. Create a custom post type either in a custom plugin or use Pods or Magic Fields 2 to create a custom post type that stores the usernameid and test then have them enter their user id and take them to their results page.
2. Use Gravity Forms (or similar) create a page where grades can be entered then create a simple login for each user.
3. Get advice from a WordPress Developer or hire someone with the skills to accomplish your task.
