UWorld, LLC

UWorld is a global leader in online learning resources, specializing in test preparation for high-stakes exams across various professional fields. Founded in 2003 by Dr. Chandra S. Pemmasani, the company originated from his personal experience as a medical resident seeking better quality and more affordable study materials for the U.S. Medical Licensing Examination (USMLE). What began as a passion project in a dorm room, initially called USMLEWorld, has evolved into a comprehensive educational technology provider. The company rebranded to UWorld in 2014 to reflect its expanding offerings beyond medical exams.

UWorld's core mission is to deliver high-quality, exam-like practice questions and detailed explanations to help students and professionals succeed. The company employs a team of over 750 professionals, including accomplished doctors, nurses, lawyers, educators, finance experts, and scientists, who develop and refine the educational content. UWorld's approach emphasizes active learning, a research-based methodology designed to engage students throughout the learning process and improve retention and critical thinking skills. Their resources are designed to mirror the actual exams, providing students with an accurate understanding of what to expect on test day. The company serves a wide range of students preparing for exams in accounting, finance, graduate school, high school (including AP® and Digital SAT®), legal, medical, nursing, and pharmacy. Some of the specific exams UWorld provides preparation for include the CPA®, CMA®, CIA, CFA®, CMT®, MCAT®, SAT®, ACT®, AP®, MBE®, LLM, MPRE®, JD-Next, UBE®, USMLE®, UKMLA®, COMLEX®, ABIM®, ABFM®, PANCE®/PANRE®, NCLEX®, FNP, NAPLEX®, MPJE®, and CPJE. UWorld is committed to innovation and continuously improves its resources based on user feedback. The company has expanded its reach through acquisitions, including RxPrep and Themis Bar Review in 2020, and Aspen Publishing in 2024. UWorld also has a philanthropic arm, UWorld Cares, which provides scholarships and product donations to students in underserved communities.
