Finally I passed CCNA exam with score 907. First time I scored 815 because I answered one lab incorrectly.
Most difficult part to me was the language. English is not my native language so I had to read questions several times before I understood it

Also ISDN was quite hard for me to remember. Thank god it wasn't on the exam today!

I spent about 2 months to prepare for the test. Last 1.5 weeks I read allmost continuously.
Passing the test was like a big stone rolled of my back
