Organic chemistry is famous for its volume: dozens of reactions, each with its own reagents, conditions and products, and functional groups you have to spot at a glance.
Space Repeat writes formulas and reactions properly, with subscripts and reaction arrows, and reviews each one right before you'd forget it.
Free to start. No credit card required.
Orgo is cumulative: second-semester reactions assume you still know first-semester functional groups and mechanisms. Students struggle when early material fades just as new reactions pile on top. Spaced repetition keeps the whole reaction list active with short daily reviews, so the mechanisms you learn later have something solid to build on.
New accounts can add a starter deck for organic chemistry in one click, written with real notation. It's an ordinary deck, so you can edit them, add your own cards, or import the ones you already have from a CSV file.
Shown the way Space Repeat shows them, formulas and all: one clear question, one short answer.

Answer
Make a card for each reaction as it's taught, with reagents and conditions written exactly. Small differences, like heat, a bulky base or a protic solvent, change the product.
Review daily through both semesters. Organic chemistry 2 rests on organic chemistry 1, and a reaction you still know is one you don't have to relearn the week of the final.
The algorithm tracks every card and shows it again right before you would forget it. No manual planning required.
Fractions, integrals, chemical equations and highlighted code look right on every card. Plain text works too.
Every feature, spaced repetition included, is free to use while Space Repeat is in beta. Early users will be looked after when pricing arrives.

Yes. New accounts can add starter decks for organic chemistry: Organic Chemistry: Functional Groups. They're ordinary decks, so you can edit, add or delete cards, and write or import your own alongside them.
Yes. Write chemistry inside \ce{} between dollar signs, like $\ce{CH3COOH}$ or $\ce{A + B -> C}$, and subscripts, charges and reaction arrows are formatted for you. For structures, add an image to the card.
One reaction per card: starting material and reagents on the front, product and conditions on the back. Make a second card in the other direction for the reactions you're most likely to be asked to plan.
Yes. The MCAT tests functional groups, reaction types and lab techniques, all of which suit flashcards. Keep an organic chemistry deck next to your other MCAT subjects and review them together each day.
How to Use Flashcards for Organic Chemistry
Organic chemistry is mostly hard because of volume. Flashcards handle the part that really is memorization (functional groups, reagents, reactions, conditions), so your study time goes into mechanisms and synthesis.
How to Memorize Formulas (and When You Shouldn't)
Some formulas are worth knowing cold, some are better derived, and some can stay on the formula sheet. How to tell them apart, and how to make the ones you choose actually stick.
Space Repeat vs Anki
Anki is the most powerful spaced repetition tool ever built. It's also one of the most frustrating to set up. Space Repeat was built for learners who want the same scheduling logic with a fraction of the friction. Here's how the two compare across the things that actually matter.
