This plugin do the following tasks assuming Gravity form installed and Score form created:

• Create a custom checkbox in the “Final Score” field general settings says “This field will hold the final score”.
• Create a registration system where users can signup and login (do not use a plugin for that).
• Once the user logged in, he should be redirected to “Account Page” and find the Gravity Forms form that you have created and he can submit the form. However, once he submitted the form it should not show up if he refreshed the page.
• Once the legged-in users only submit this form create a hook that gets triggered before the entry is saved to the database to check if a field is the final score field and assign the sum of (Score 1 + Score 2 + Score 3) in it.
