Learn the images, not just the words.
RheumLens is a free, image-based rheumatology question bank. Practice recognizing the real clinical images that show up on the boards — crystals under polarized light, rashes, radiographs, ultrasound, and more — built on the ACR Rheumatology Image Library.
Image-first questions
Every question is anchored to a real clinical image. See it, name it, learn what clinches it.
Board-style reasoning
Plausible distractors and explanations that tell you exactly what to look for and why.
