dfrost,What was your OAR? If that's lower it may indicate the Math/Reading/Mechanical sections were where you did not score as well.
For the Terrain ID, this video was helpful. The strategy I used was to find a straightish line on the terrain and rotate the compass rose I made to align with that. I prioritized accuracy over speed on that section and just worked as quickly as I could without running out of time on each question (usually had about 2/3 of the time left on each question with this strategy).
My OAR was a 43. How does this factor into the 3 scores you receive?
I have been using the strategy from the video you posted and enjoy it. More than anything I just need more reps and comfortably with that section. I was scoring 80% and above on the simulators but never confident in my selections. I think I went to fast and urged to get the test over with.
