Wrote the 5.5 for the first time the other day and finally passed this exam ! 
(3 attempts total, 2 on 5.1, 1 on 5.5)
With the DCD finally out of the way I can focus on my DCX and getting more material into the simulator. I am also trying to build a DCD study workshop, so hopefully will have more time to finish that up now and get it out
Look forward to getting some updates done
