I took the 8 hour, the Seismic, and the Surveying exams all in October 2016. Passed the 8 hour, but failed the other two. I wasn't surprised, as I spent most of my time studying for the 8 hour.
This April, I took the Seismic and Surveying again. I feel more confident this time around, but still not totally sure lol. Hopefully, I won't have to return for a third time this fall...
