See here if you are wanting a tutor response https://opentuition.com/topic/1-month

I would suggest that this is a very personal decision. My general view would be that you should probably postpone attempt to March sitting. If you want to take another paper along with audit at the March sitting, I would suggest this will be easier than sitting Audit in December. I would strongly also advise asking the tutor's opinion by asking in the link provided in above response by Kim Smith. Notwithstanding all I have said above, I think it would probably be possible to take above exam in December and pass. This would probably involve a number of hours study every day from now till the exam even if you have an existing knowledge and skill/experience in the field of Audit.Hope this was of some use to you.

In addition to above (and no matter what you decide with respect to undertaking the exam in December) please also see following article about strategy for paper selection- https://opentuition.com/acca/plan-your-acca-exam-journey/ I think you will find it very useful.
