CCNP done as of this morning. Studied official Cisco Press books starting in January. I also used Chris Bryant's series on Udemy.
Took the exams in this order:
Route (passed 1st time) - April 2015
Switch (passed 1st time) - June 2015
T-Shoot (failed once with 806, passed a week later with 951) - September 2015
I downloaded the blueprints for Route and Switch and pasted them into OneNote, then read about all of those topics and filled in notes underneath them.
For T-Shoot, I memorized the topology from Cisco:

Happy to be done with this, and moving onto CCIE. I'll take my R&S written in June 2016, take Narbik's 10 day bootcamp around October/November 2016 and Lab in January 2017.
