Portal 2 - Phase 1 - sp_a3_01 - Route
This was based on Gocnak's route. I changed the start to use the portal that is on the upper area, because it is easier to see the far away portalable spot on the high up catwalk. You simply jump off the trash on the ground to be able to hit that ceiling portal. I used his route the rest of the way. Excuse the sloppiness near the end of the level. I was tired and didn't feel like redoing the attempt again. It isn't a difficult level overall.
