Hi Manu,
With fewer than ten days to go, the most useful thing is probably to complete the remaining PM Prepcast questions through your fourth practice exam and quizzes, continuing to review in detail afterwards.
I would also advise spending some time to establish a good time-management strategy for the real exam (having time targets for various points on the countdown timer, having a plan for when to stop and return later to more challenging questions using the 'review' option, etc.).
My previous question regarding how you fare when answering the quiz questions without any time pressure was to see if that was an important factor for you. I don't know how to reduce question answering time rapidly, but I suspect that more and more practice (through the remaining quizzes and practice exam) should help in the long term.
One of the most useful things to me -- I emphasize that, because we all learn differently -- when I started my PMP studies was building up a library of flash cards, a little each day over several weeks. I used all of the content from the glossary of the Agile Practice Guide and PMBOK7, plus other terms culled from the November 2020 edition of The Scrum Guide (Schwaber & Sutherland), which I think you can find free online. I used the cards whenever I had a free moment and I felt at the time that my ability to choose the correct answer from the options in PM Prepcast quizzes increased a great deal, thanks mainly to being so familiar with the terms, definitions and the language involved. With very little time left, I would not necessarily advise you to spend it in creating the many hundreds of cards involved. You may be able to find ready-to-use collections of PMP-themed cards available online, even for free, on flash card applications with crowd-sourced content. (I believe that typing them all myself helped me to absorb the information better than if I just read the cards and practiced with them, but that may be wishful thinking on my part.)
This is just what strikes me as possibly useful to you at this point in your exam preparation. You're free to ignore any and all of it.

I hope others with other perspectives will jump in.
Wishing you well in this challenge.
