Hi all,
After a painful 45 days of waiting, I've been officially informed that I've earned the GSE.  I'm number #202!
I created a thread last Summer about the 
GSE Multiple Choice exam.  After passing the multiple choice exam, I went on to earn the GCFE and GCCC as part of the final stretch of the MSISE program.
With those certs out of the way, I really began focusing on the GSE lab this February (about 3 months prior to flying out to D.C. to take the 2 day hands-on portion).
The 2 day/16 hour lab was the most challenging certification exam/process I've endured.  The lab covers 
a ton of content and you're forced to work under pressure while exercising excellent time management skills.  Like all GIAC exams, I'd say that the whole thing was fair, and definitely aligned to the 
exam objectives.
I created a GitHub repo back in February to serve as a gathering ground for exam tips, resources, and methodologies.  I had a few collaborators who contributed too.  The repo is organized to align to the primary GSE objectives and sub-objectives.  It's really meant to be an aggregate for things useful during preparation:

Upon finishing the exam, I had to sit with mixed feelings and anxiety that plagued me for weeks.  Just like those before me, I don't think anyone walks away from the lab saying, "I feel great about it".  There were 25-30 of us who took the lab this most recent round, and 9 of us passed.  I feel 
very fortunate.
Phew.
