Method 1 (Speed)
Stand still for half a second, and let the zap drone immediately to the right of you pass the corner. Now quickly hold right, and jump on that slope to go above the drone and the floorchaser. You will now be in the room with the exit switch. Drop down to the bottom and activate the floorchaser there to the right side. Quickly go back up to that slope right above the floorchaser, to the right side, and drop down from that slope. You will land on the ground, touch the switch, and run up the left wall before the floorchaser catches up. Jump around to dodge the zap drones, then hurriedly walljump upto the top area. As soon as the top drone moves away (there will also be a drone at the bottom heading upwards), walljump off over the zap drone. The remaining drone next to the door will head downwards, so jump to the exit.
