i'm by no means brilliant, but i did work hard.
i'm scoring around 73% in phys, and i also read RR path but I also read kaplan physiology and attended the kaplan physio lecture as well. I personally think that the kaplan physio book is the best one out there as it is very well written and has excellent diagrams and clinical application. try picking up a kaplan physio book if u can, it's a beast to read through-almost 600 pages or so, but a concentrated effort could put you through it in close to 3 or 4 days.
best of luck to you.
