Booking and giving Plab before graduation to get into UKFP

I’ll be graduating in july, 2023.I’m willing to get into UK through the UKFP. If everything goes well, in order to start my FY1 training in August 2024, I’ll have to give Plab 1 before November, 2023. So, when should I book a date for Plab 1 in order to complete it before Nov, 23’?
