I am very surprised that your ATO can’t tell you the answer and have no experience of (H) but in an integrated (A) environment you should get nothing until the entire course is completed and all tests passed.
I would very much doubt they will kick you off the course if you did fail - what would happen if you had a partial pass? But if that were the case than you may be able to convince your service to fund any remedial training and a second test or pay for it yourself to complete it.
Your ATO will probably not put you up for test until there is a strong probability of you passing anyway so hopefully you’re worrying about nothing.
