Player 2 : Once player 1 has reached the light bridge, set your portal on the elevated square panel in the upper left-hand corner of the floor and your next portal above the Faith Plate.
Player 2 : Leave one portal above the Faith Plate, but set a second one either on the left or right-hand side of the floor opposite the Faith Plate. Now hit the plate and you'll land by the light bridge and in a position to join player 1 through the portal.
Player 2 : Make your way down the light bridge but stop once you're on the permanent version. Ask player 1 to set a portal back on the lower wall panel (near the water) and use this to reach the start again. For the final time, place your entrance portal directly above the Arial Faith Plate.
