UPDATE: In comments, someone posted this link: http://www.midnightmonkey.co.uk/blog/blogging/?page_id=5. It looks good to me too.
I passed the MOSS technical exam today, entitled "Microsoft Office SharePoint Server 2007 – Application Development". I found the exam to be pretty rigorous and that it matched up quite well with Microsoft’s preparation guide.
I’ve been working with MOSS on a daily basis and nothing beats actual hands-on experience for all of these exams.
That said, I took note of what I was studying as I studied. I believe that all of these resources are helpful, particularly as a means of reinforcing that hands-on experience.
Many of those links led to more links and I tended to follow them up to about 3 levels deep.
I wouldn’t say that everything I read directly applied to the exam, but I don’t regret reading any of it and even if some bits were not directly relevant. It’s all good stuff to know and I strongly recommend the material for all aspiring well-rounded MOSS developers.
