ACCA Advanced Diploma advice please



I am part way through my ACCA F papers, exempt from F1-F3 and have sat and passed 3 others. I was wondering if it was acceptable/possible to just sit the F papers to F9 and not complete the P papers. As much as I would like to get to the end I am starting to really struggle with working full time and studying. I have already sat the F7 and F8 papers and so I don’t think I am eligible to apply to complete the Bsc Degree at Oxford Brookes but I see that on the ACCA website the F papers alone will give you an Advanced Diploma. I just wanted to know if anyone else had stopped at F9 or if this is a real waste of time and I should push on?

Thanks in advance for any help or suggestions!
