WBS requirements and time to receive the degree

Hi
I am left with one exam and waiting for my exam result. I will be submitting the 2 years PPD + 5 months PPD (for current PPD year) + WBS.

My queries are -
1- Do I need to submit full year of WBS or 7 months is sufficient and by doing this I will be able to complete 3 years of work experience & 7 months WBS and 5 months PPD for current year)?
2- Can I submit the WBS in the meantime so that it will not delay the process once I am done with my exams or I need to submit it along with the final sign-off?
3. How much time it will take once results is out and submitted all the PPD/WBS requirements to IFoA to receive the fellowship degree?

 

These look like questions for the Institute.
