Hi guys, just signed up after finding this very useful site after failing my 640.
I got 450/700 points after taking the test and I can easily say that I failed from not labbing enough and just focusing on the practice book tests I had (R2) and skipping CS/FS, where a lot of questions amusingly was on CS, but I did understand the gist of the questions but the answers provided didn't have enough memory on some of the commands to answer.
I am already half way through the second practice book of 642 and it has helped a lot on DNS and a few other things (currently just about to go onto IPSEC) and thanks to the resources here I have nuggets for video reference and plan to get through all the book by the end of this month and then spend an entire month (looking at 4/5 hours over 5 days a week on average) of February of memorising all glossary meanings of commands and labbing on each lab test from the practice book and some online things.
I generally have great memory and understanding of IT stuff, having being an IT Technician and working in three schools (still working in one now as a network coordinator) and started this since I was 17 (22 now). Do you think with the above plan of spending a month of labbing and learning all commands should be reasonable enough if I have a feel of things? I plan to go back to 640 after I passed and actually read the final 200 pages I discarded (Damn you CS) and watch the nuggets with it and do more labbing for a month on that. I will also do a course for the 646:server admin and then revise on the book because I want to get my ITP certification before it expires at the end of July. Hopefully then with 6 years experience and my enthusiasm/passion for server administration I can then jump onto the next posistion and then reap the benifits of being able to live more comfortably

Thanks in advance guys, sorry for the rant ^^
