Written Exam Simulation

Yesterday night i use a software that simulate the written exam, and  my score was 577/1000 in order to get the written exam you need to get 800/1000.

The result doesn't scare me, i know all the stuff but about 25% of failed questions
were due to the fact that i don't read all the question (i want to answer just reading the first lines).

For the other 25% we can say 10% is due to the fact sometimes i don't want to do some simple calcul (eigrp metric, binary conversion, etc ...) for the rest
i need to make some revisions :
-going deeper in ospf make me forget some simple stuff (loop guard, vtp, root guard : L2 things)
-going deeper ipv6
-going deeper in multicast (pim-sm, pim-dm, msdp, auto-rp)
