The resource market keeps growing. Every few months there is another question bank, another set of notes, another thing the group chat says you need. Staying focused in that environment is a skill of its own.
Whether you need more than one bank depends entirely on which exam you are sitting.
Step 1: UWorld is enough
UWorld plus a good explanatory source plus First Aid will get you there. The people who score highest on Step 1 are not the ones who added the most resources, they are the ones who got the most out of a small set. Adding a second bank to a Step 1 plan almost always costs you focus without giving much back.
Step 2 CK: three banks, in this order
Step 2 is different. Volume of clinical exposure matters more, and the three main banks each cover slightly different ground. The order matters as much as the choice.
First: UWorld, full first pass
Work through it system by system on your first read, with Inner Circle Notes beside you as your reference. When you finish, go back over your incorrects and flagged questions, then take your first NBME to set a baseline.
Second: CMS Forms, all the online ones
CMS Forms are the closest available thing to real Step 2 CK questions, written by the same organisation that writes the exam. Do all the online forms. If your first NBME flagged specific weak systems, do the offline forms for those too and review them properly.
Third: Amboss high-yield plans, final weeks
Use these at the end to fill what UWorld and CMS left behind. Amboss is especially good for the areas people quietly underprepare: ethics, preventive medicine, quality and safety, vaccine schedules, screening guidelines. All reliably tested, all reliably skipped.
The highest scorers did not cover the most resources. They covered the right ones completely.
Want this as a plan instead of advice? If you want a day-by-day schedule built around your own exam date and your own weak systems, that is what Dumirieh mentorship does. You can read my full story on the about page.
