A 60-second look at the app
Weekly goals, topic-by-topic practice, and a challenge mode with a live leaderboard — this short walkthrough shows exactly what studying with OrganicChem Quiz looks like, from picking a category to reviewing your mistakes.
Try it yourself →Why students use it
Built like a study tool should be
Mechanisms, not memorization
Every question is built around understanding arrow-pushing and reaction logic — not recalling isolated facts.
Bite-sized daily practice
Weekly goals, streaks, and a mistakes queue keep review short, repeatable, and actually finishable.
Written by a working chemist
Every question and explanation comes from a practising postdoctoral organic chemist, not a generic question bank.
Books
Chemistry textbooks by the same author
Two problem-driven textbooks that go deeper than the app — full worked mechanisms, step by step.
About the author
Made by a chemist, not a template
Written and built by Marcos San Segundo, PhD — a postdoctoral synthetic organic chemist at the University of Copenhagen, working on photocatalytic chemical biology tools.
