A Layers panel you can't break. Reorder it, hide things, and find out what Opacity does that Fill doesn't. The exam asks about that one every single time.
Top of the list is the front of the picture. Use the arrows to move a layer up or down and watch what gets covered. The eye hides a layer without deleting it.
Your name has a stroke and a drop shadow on it. Those are layer effects. Slide each one and watch what it touches.
Name and credit line live in the TYPE group. A group is a folder: it organizes. A link is a chain: linked layers move together even if they live in different folders. Turn the link on, then nudge the name.
Three questions written the way the exam writes them.
