Well i finally pulled my finger out and took my JNCIA-JunOS today.
Glad to say i passed with 88%.
As this is junipers entry level exam, the skill level is exactly that...erm entry level

. Covered the basics of JunOS and the areas covered in the fast track pdfs. The track pdfs cover everything you need to pass this exam imo. I also had some hands on experience at work and using olives in GNS3.
Good luck to anyone else studying for it.
