Currently for the MCM SQL Server 2008 Knowledge Exam, there is a built in delay in the test taker getting their results. This is due to the fact that the exam was listed as Beta during publishing to Prometric. There is then a once a month rescored that occurs, with your results being sent to you in the mail.
This will change for the MCSM: Data Platform Knowledge exam (88-986). We cannot change it for the current MCM Exam 88-970.
However, I understand that after you have taken the lab exam and endured that stress the last thing you want to do is have to wait 30 days to hear your results.
So, effective today 3/21/2013 the restriction on the delayed reporting of Lab Exam (88-971) results has been removed.
Now you can expect to receive your Lab exam results in around 5 business days (or less when possible).
