Hey, I’m working on my create project and I want to know if there is a way to pick a random screen after I get the correct answer and not get a duplicate screen because the app is a quiz ?
Don't display a random screen, just a random question on the same screen. Unless you want to do a quiz with only ten screens, because this screen limit exists in AppInventor.

My app is a cartoon character quiz and the user has to guess the character based on the picture. So would I randomize the picture?
Have you seen the President's Quiz tutorial Dennis? http://www.appinventor.org/bookChapters/chapter8.pdf .
The app is partially based on displaying a picture and asking a question that relates to the image. The example may help you design your app.
Here is a link to a discussion showing how to add a counter to keep track of right/wrong answers that might be helpful Sumatoria de puntos (in the President's Quiz tutorial)
