Welcome @leroyweatherly3 !
Can you clarify what you are looking for? If you are just looking for the answers to the online unit 3 test, you should be able to see them when you are looking at studio.code.org as a teacher. When you click on those bubbles you can see the answers there.
If you are looking for a separate study guide that is supposed to prepare students for the unit 3 test in studio.code.org specifically, that I don't have but, maybe someone else here has created one! Code.org doesn't specifically have study guides created for teachers but a lot of teachers individually will post them as they create them here which is fantastic!
Does that help?
