I started Rx in January to get used to seeing how each piece of information in FA can actually be turned into a question. Rx is mostly 1st or 2nd level reasoning. 1st level reasoning might ask for the diagnosis, second level might assume you know diagnosis and ask for the treatment. UWorld went 1-2 steps further (although there are still some easy ones) and would assume you knew the diagnosis and treatment and then ask for the side effect of the treatment or ask for how to treat the most common side effect. So I ended up doing about 800 Rx questions up until spring break (March) and supplemented with about 10-20 UW questions per week leading up to spring break. This got me used to common questions with Rx while easing me into answering more difficult questions with UW. From the end of March to June, it was all UW (and practice tests during dedicated study). I think I ended up not even finishing every question (still had about 100 left), but I used it as an assessment tool. I would always create a test-taking environment and would only do questions on the topics I felt like I studied enough. Started with cardio studying and would add cardio questions once I finished studying, started pulm studying and would add those questions once I finished. By the end I was doing all random questions for every subject but worked up to that point over time so I wasn't blind-sided by things I hadn't studied. I think I added biochem from the start so it forced me to study those questions early on rather than trying to cram it all last minute. Did the UW stats module (takes a day or two) and read that FA section before adding those into the mix, too.
Main study resources were pathoma, FA, UW, Rx, and I think I added some BRS physio for high yeild topics. Key was to use these resources over time and to aim for understanding and repetition rather than sitting down and reading it straight through. You need to learn how everything is connected (which takes time and effort, not just going through the motions). I also attended all my lectures and felt like studying for lectures was beneficial to my overall fund of knowledge. For me, I unbound both my pathoma and FA, 3-hole punched them, and put them in separate binders so I could take notes about each UW topic (usually on questions I got wrong or didn't fully understand) and add it to the appropriate section of either pathoma or FA. For Rx, I would just fly through the explanations and burn through questions. To really get the most out of UW, you need to fully read and try to understand the explanations (in my opinion).
My friend did a similar study strategy the year before me and we both scored in the low 250s. I'm not too good at taking standardized tests but starting to study early and consistently made all the difference for me. Hope this helps!
