Hi my friend
I've just downloaded the "Student guide" from a website searching on google.com. I also studied using the "CISCO ISCW Official certification guide", but believe me....the "Student Guide vol 1 and 2" is 2 steps forward. You will find a lot of information very useful for the exam that are covered in a fluffy way in the "CISCO ISCW Official certification guide".
The "Student guides" I'm talking about do not come from the ciscopress.com website.....they are used during the official Cisco Certification Training....so try to have a look also in the "share" section".
The version of the "Student Guide" I used has been the 1.0 (from 2007). The same is valid for the BCMSN (student guide 4ever). For the BSCI instead I used "Authorized_Self-Study_Guide_BSCI_642-901_3rd_Ed" and is a very cool book.
Hope u all the best for the exams....
Tomorrow I'll start to study the ONT....hope to succeed on it as well....
