Quick Study is a bronze trophy in Uncharted 3: Drake's Deception. This trophy can be earned during Chapter 2. Start out by inspecting every display case on the first floor by pushing up on the d-pad when you stand next to them. Continue up the stairs and inspect the one on the staircase landing. When you reach the second floor, make sure not to look at the display case Nate's actually looking for (the one in the middle of the room). You don't have to inspect all of them.
