The most feared pre-med course — made visual and interactive. Free simulations, a full interactive ebook for all 22 chapters, and timed practice sets. Whether you're in Orgo 1, Orgo 2, or prepping for the MCAT, everything is free.
Two chapters — Alkene Reactions (24.5%) and Stereochemistry (23.9%) — make up nearly half of every Orgo 1 exam. Add Acid-Base (17.8%) and Functional Groups (13.7%) and four chapters account for roughly 80% of what's tested.
CU Boulder, Dartmouth, MNSU & compiled practice archives · n = 1,059 questions
Early sample · aromatic + carbonyl-heavy archives · n = 66 questions
Note: our Orgo 2 sample (66 problems) is much smaller than Orgo 1's (1,059) — most of the free university archives we found so far skew toward Orgo 1. This will get more representative as we source more Orgo 2 exams.
