I was hoping to find an answer to the exact same question. So far, we have covered Skin, Musculoskeletal, CV, Respiratory, Renal, Heme/Onc and are halfway through GI. I was thinking about getting USMLERx and doing questions on only the systems and/or classes that we have covered so far. I wanted to devote ~1-2 hours every morning doing question blocks on what we've covered, since this will really help me get through FA (I've already read the system chapters 1x each, but I want to get through it ~5x total before my exam in June) since I have a tough time just sitting down and reading a chapter in FA without any questions to solidify my understanding. I wanted to get through USMLERx by March and then start UWorld and do that for two months until my exam. Does anyone have any comments on this? I've debated beginning UWorld now vs. USMLERx now and saving UWorld 'til later, but I'm just not sure.
Any help would be greatly appreciated!
