This is the third course for the Portal 2 co-op campaign. These chambers are where the difficult, in my opinion, puzzles start to begin. The light bridge is a very neat mechanic, and it is way too much fun to mock a turret when you have a light bridge shielding you.
These video guides should make it an easy task.
Note: I will keep looking for the split screen videos and update this solution once I find them available.
