Although that's an incredible achievement

, lots of people don't get TC offers even after they've completed a VS and it's probably quite a valid worry. So many people here have done a VS or got to AC and then had the rug pulled under them last minute.
OP should focus on the things they can control such as preparing for the VS scheme, submitting apps elsewhere if they are anxious or feel the need to. I'm sure they will do just fine but relaxing when you haven't gotten over the last hurdle of the recruitment process is probably a mistake that some people make!
Good luck OP
Also, I'm not sure how you got your TC offer but if it was somewhere in the recruitment process before you completed it that's really rare and candidates should probably know that. Although it's massively impressive!
