Today I officially became LPIC2 certified!
Both exams (117-201&117-202) were not as hard as I expected, still challenging though.
My best advice for people who planning to take the tests in the future is PRACTICE!
Build your own Linux environment of different distro's, install, configure and explore in depth.
Only by practical experience you will understand how things really work.
Some good sources I used for my studying:
Awesome in-depth tutorials focused on LPIC 2 Test (material was re-newed in 2010):
LPI Tutorials by IBM (offering tutorials for all 3 levels).
