There is a lot of speculations going on with the timeline after the test. I have seen people finished their tests from Dec/Jan still waiting for any communications, and at the same time I've seen people's status changed to DM in just a day. In the meanwhile I think you should just have some patience, and see what happens this week. As I mentioned before,
@his*marty 's status changed to DM almost 50 days after the exam so no one has any idea what is going on exactly. However it is concerning that they did not receive the passing result and it's been 20 days. I hope you will get some updates soon.
