We built USMLEDx because our USMLE coaching students were looking for an easier way to assess their USMLE prep progress & find their weaknesses without having to waste their NBME or Qbank assessments far too early. With this product, everyone now has a simple way to assess their USMLE exam readiness, quickly find their weaknesses, and speed up their USMLE Step 1 or Step 2 CK exam prep without having to throw away the precious NBMEs that should be reserved for later in the prep process.
