I recently met up with one of the Swiss PASS Chapter members who is looking to undertake his SQL Server 2005 Certification exams.
Apart from wishing him the best of luck, we reviewed a lot of the content generally covered within the MOC syllabus' (I'm an MCT), SQL Server architecture and walked through a lot of areas that he wasn't 100% clear on. We did this over a few hours in the evening after work, and it looks like a great thing for me to do again for any Chapter member who needs that "review" in preparation for the exams.
I am by no means encouraging people to come to me to to take them through the whole technology base, but if you're motivated and have done enough of your own groundwork then I'm happy to have a free evening session where we could have a 1:1 discussion, walkthrough and hands-on review of the SQL Server topics of interest.
If enough people subscribe to the offer for help, then we could look into having a workgroup type approach to it, similar to what we used to do at Uni, order in some pizza and work through it all together.
Ping me if its relevant or of interest, my contact details are on the Swiss PASS Chapter Website. Remember the offer is free, this isn't a money-making scheme, but don't abuse it ;)
