I skip the get to the other side one unless I have ring of the wild hunt on me.
This one seemed impossible once I got to the 5th level of the challenge, right up until I slotted Rapid Maneuver. I would just identify the correct order for the pylons (sometimes it only uses 5 which is nice), pop Rapids and just zoom through. I have yet to fail this challenge since then. Just remember to swap Rapids back out for the skill it replaced!
