Congrats on the pass.
FAR gives you a good basis for AUD. I sat for FAR and then crammed for Audit in 3 weeks by watching all the videos and jumping straight away into the MCQs.
Did 1000 MCQs in 2 weeks, and then scored an 88.
I'd try to up your timeline a bit to knock out AUD before busy season starts, if you work in tax.
If you have to travel a great deal for your exam, then it doesn't make much sense to rush, so please disregard if you have extra expense.
