ACCA Last two exams - opinions?

Hi everyone! Just wanted to get an opinion on something. I am currently an ACCA student and in the processes of completing my ACCA, i have two strategic exams left to do, SBR and an optional exam. I am currently working full time in a big four firm also a full-time mum to a five-year-old xD

I was looking for some advice on:

1. Should I do SBR and then an optional? (I have already done AAA)

2. For the optional should i go for AFM or TAX?

3. I have already attempted both SBR and AFM in the past, but it was a quiet a long time ago and i have forgotten everything - Have the exams gotten more difficult?

4. I am currently in Sydney and would was looking to tuition to suit my scedule but are also reliable in terms of teaching the content and exam prep. As i will be receiving financial aid i would like to pass on the first attempt haha

5. anyone else wo has gone through this? how did you go about it to ensure a successful attempt?

Thanks a lot :)
