It's pretty much guaranteed this application will be accepted due to you being an admin and also making an above average application, even if you haven't played anything in command other than CE at all.
I really urge you to get more practice, even after this gets accepted, as SO and XO.
Here's some realistic questions.
1. You have a full team of MPs on high pop. You have a bunch of round start shittery which the marines have no regard for OOCly in rules. The MPs are not responding to your calls and failing to make arrests for some unknown reason, what do you do? Perhaps investigate?
2. How do you deal with your marines, mainly delta, metarushing?
