I am studing for CCNA. I bought the CiscoPress Books (Intro and ICND). I also bought the Selftest Exam Engine but it didn?t like me because it is very limited, I got over 90% on all my attempts on this Engine while I got only 80-85% on the Demo Exam of Cisco Press.
But my question is:-
How can I improve my Troubleshooting skills?
Is this objective included on any of the Simulators Software Boson or Sybex or they only do some labs? What would be better?.
