hey greg
Congratulations!
Are you male right? Yes you are tentatively booked on Jan, I had the same also. But my departure to Doha is on Feb 20, so yours will be subject to changes.
After your medical, you have to wait for 2 weeks to be cleared if your medical results are all okay/normal and they will advise you if some will be repeated.
But don't worry, everything will be okay soon.
It might be on February also. see you soon
