Question about when to use Après que and Après avoir

Question

Hi there,
So I know you can say "Après avoir fini ma rédaction, j'irai me coucher" 
q1. But can you also say use "Après que" here or do you need a change of subject? (Like: after I've finished my homework, my teacher will mark it")
q2. If you can use "Après que", is it correct to say "Après que je finirai ma rédaction, j'irai me coucher". Or "Après que j'aurai fini ma rédcation, j'irai me coucher"
q3. Is Quand interchangeable with Après que? I know that the hidden future rule applies to Quand when you're saying "Quand j'aurai ma rédaction, j'irai me coucher". Like q2, would it not make sense to say "Quand j'aurai fini ma rédaction, j'irai me coucher"?

Thank you.

Hi Ry,
Before answering your questions , it's important to note is that 'après que' is followed by a tense in the Indicative mood (unlike 'avant que' which is followed by the subjunctive) .
The answers will be :
Après que j'aurai fini ma rédaction, j'irai me coucher. 
or 
Quand j'aurai fini ma rédaction , j'irai me coucher.
You can also say:
Lorsque/une fois que j'aurai fini ma rédaction, j'irai me coucher.
You have 2 actions in the future and the first one is 'antérieure' (prior) to the second one, so you have to use the future perfect and then the future.
Hope this helps!
