18 month expiry and retake questions

I have BEC that will expire on Oct 13. I will also be taking FAR on Oct 13. My chances of passing FAR is low but given that FAR is my last part I am taking a punt. If I pass FAR I am done. But I have 12 days to cover FAR and I have not really started. Good thing is that I am not working at the moment.

Am I able to retake BEC this window – before Nov 30 without know the FAR results?

My plan is to study for BEC after taking FAR (assuming that I do not feel good about the FAR exam) and take the BEC Nov 30.

Then I will leave Dec, Jan, Feb to prepare for FAR which I will take end of Feb.
