This test chamber is the thirteenth bonus level of the game. It is taken from Portal: The Flash Version MapPack. The challenges of this level are unlocked when the test chamber is completed once.
By using the Portal Gun, place one of the portals on the X mark that's above the Turret and the other portal onto the walls or the flood that is portalable (has to be within your reach).
Fall onto the Sentry Turret by going through the portals and knock it down.
Get back on the floor, avoiding the turret that is behind the Light Bridge's bullets.
Shoot a portal trough the Light Bridge and go inside the room where the cube dispenser is.
Using the cube, redirect the Energy Pellet into the catcher.
After you have redirected the pellet to the catcher, while crouching, crawl into the small hole what was used to transport the pellet to you (with the cube).
Drop down into the pit and place the cube onto the Button.
Drop down even deeper and quickly avoid the Turret.
Kill the turret.
With portals, go back and grab the cube from the button and place it on the other button seen in the same room with Goo.
In the way, over the goo, by the corner, portal onto the sinking platform and bring the cube with you.
Wait for the right time and jump onto the platform.
Drop the cube and portal onto a ledge.
Grab the cube back and quickly jump trough the portal previously placed.
Drop the cube and crouch behind it. This will keep you safe from the Turret.
Place a portal behind the turret and, avoiding the turret's bullets, knock it down.
Peek over and portal onto the other sinking platform (with the cube).
Quickly jump onto the ledge and knock the turret down.
Peek over and portal onto the other sinking platform (with the cube).
