Now the questions are:
1: I didn't received any oath notice as of yet
2: I have the Whitten text exam on same date and same time at 10:02
How can I perform my written test and take oath at the same time
Then it's probably a mistake - they are not good at looking at a map, thought Airdrie is 3 days drive away. Anyway you don't anything to lose. Just go there for the test, and if they ask you to do the oath right afterwards, BINGO!
