Are you hoping to defer again?
If so it is bad news I'm afraid.
There is no chance of a second deferral. You can only defer once.
Your only option is to apply for excusal but that is a very high test.
To be wholly honest, you don't meet the criteria at this stage. You would have to prove that two weeks off would have a literally ruinous effect. Excusal is much easier for people who are likely to be needed for trials that last up to six months.
Normally you would have to show literally unusual hardship rather than just mere inconvenience.
You need to try to find something unusual about your application or it will be refused.
If you cannot then it will be refused.
Applications on the basis of hardship are pretty strictly scrutinised.
Can I clarify anything for you?
That is probably right I'm afraid.
You may as well try though. There are no consequences for trying and failing.
