Player 1: Place a portal on either of the walls to your side, then fire a portal onto the wall right beside the red plunger that's beside the permanent light bridge. Ask player 2 to join you on the light bridge and get yourself ready for the next part.

Player 1: Turn to your right and make sure you fire a portal at the end of the light bridge where the wall is, then get your second portal on the 2-piece wall panel that's located opposite the funnel that drops the weighted ball.

Player 2: Pass the weighted ball to player 1, then place a portal on the wall ahead of you then set a second portal on the overhanging wall panels nearer the ceiling. This will create a light bridge that'll take you right across the water, towards the exit.

Part 2

Player 1: Upon entering the second part of the test chamber, look up and to your left, you'll see a light bridge hitting the wall. Get your first portal up here, then place a second portal on the wall panel on the left-side of the room (facing the exit). Try and get it so the light bridge creates a mini 'step' up to the exit.

Player 1: Stand on the Arial Faith Plate and the vertical barrier should stop you from landing on the other side of the room. It should just be a simple matter of jumping up to the exit. But if you find your light bridge is too low down, you can adjust its height slightly to raise yourself up. Now you just need to make sure player 2 follows you into the exit.
