I passed all 4 SharePoint 2010 MCP exams at TechReady-12 (a Microsoft field employees only tech conference) and have gained following new MCP titles:
Here are the exams I passed:
It turned out that the PRO exams were easier to me than the TS'. However, without passing the TS exams, the PRO's would not be activated. The hardest one for me was 70-573, I failed the first time (scored 624) and had to re-take it.
I chatted with the guy who was managing the makeshift exam site at the conferece, he said the passing rate was about the same as his other "official" sites, around 50%. I figure since the exams for TechReady attendees were free so there would be much less stress and preparations for our Microsofties, like me, I didn't prepare for the exams at all. Therefore, we do know better about our own products.
OK, here are some tips I would like to share if you plan to take these exams:
