Using the faith plate the second time around will take your further to the second ledge where you will run into a second barrier. This drops the panel that blocked you right as you landed on the first ledge. Here place the Weighted Storage Cube in the path of the laser to block it from hitting the receiver before jumping down to use the faith plate again. Next you will need to jump on the faith plate to launch yourself up to the first ledge. This will launch you to the ledge containing a Weighted Storage Cube. Next find the drop to the right of the room, facing away from the entrance and fire an orange portal at the bottom of it before jumping through. In test chamber 10/22 in chapter 3 of Portal 2, your first task will involve placing a blue portal directly above your entrance into the chamber, seen in the pictures to the right. Note: See the achievement description below if you are trying to earn Overclocker. Now use the faith plate to launch yourself with cube towards the exit. With it hitting the receiver, the exit door opens allowing you to leave chamber 09/22. Once upon this ledge you can move both portals to the wall in-front of the receiver so the redirected Thermal Discouragement Beam can pass through. Move your blue portal to the next angled surface over to launch yourself one last time, up to the ledge where the exit door sits. Once there you can grab it and step off the ledge, using the Cube to redirect the Thermal Discouragement Beam into the white surface which stands in-front of the beam receiver, next to the final ledge containing the exit door. Move your blue portal again to the next nearby angled surface to use the faith plate to launch yourself onto the ledge containing the cube.

Hit the button to dispense an Discouragement Redirection Cube from the nearby Vital Apparatus Vent. Leap through your blue portal and take the faith plate back through to launch yourself onto the ledge. Leave the portal above the faith plate (orange) and move the blue portal to this angled surface. Find the one to the left (if you were looking from the faith plate facing the upper level) that is angled towards the small ledge containing a switch.

Once on the upper level you will find a series of angled platforms. For reference, the portal above the faith plate will be the orange portal. Keep attempting to use the pad until GLaDOS lowers the ceiling, then use portals above the faith plate and an exit over the upper level ahead. In the first test chamber of chapter four, you will undergo some more berating from GLaDOS on the “generousness of your body” as you attempt to use the faith plate in this room. Using portals once at the final ledge to get the beam into the receiver.
