Medical school is expensive, but the stress of getting in is arguably worse. Ask any premed student about their biggest hurdle, and they’ll likely point to the MCAT. It’s a beast. Most people spend months drowning in Kaplan books or Khan Academy videos, only to realize they’ve forgotten everything from chapter one by the time they hit chapter ten. That’s where the MileDown Anki deck enters the room.
It’s legendary.
If you spend more than five minutes on the r/Mcat subreddit, you'll see the name everywhere. It’s basically the "Old Reliable" of the premed world. While newer decks like Anking or JackSparrow have since surfaced with more cards and deeper complexity, MileDown remains the most accessible, visually appealing, and efficient way to brute-force 2,900+ essential concepts into your long-term memory.
But why do people love it so much? Honestly, it’s because it doesn't try to be a textbook. It’s a tool. It bridges the gap between "I read that once" and "I can recall that in three seconds during a high-stakes exam."
What Exactly Is the MileDown Anki Deck?
Let’s get the basics out of the way first. Created by a Reddit user named (unsurprisingly) MileDown, this deck is a curated collection of approximately 2,900 flashcards. It covers every single section of the MCAT except for CARS (Critical Analysis and Reasoning Skills), because you can't really "memorize" your way through reading comprehension.
The deck is organized into sub-decks: Behavioral Sciences, Biology, Biochemistry, General Chemistry, Organic Chemistry, and Physics.
What makes it special is the formatting. Most Anki decks are ugly. They’re just black text on a white background. MileDown is different. Every card is color-coded. Most include a high-quality graphic, a link to a relevant Khan Academy video, and a summary of the concept from the Kaplan review books. It’s a comprehensive ecosystem contained within a single flashcard app.
The Strategy of Efficiency
You don't have time to waste. That is the reality of the premed life. You’re juggling labs, volunteering, shadowing, and maybe a social life if you’re lucky. The MileDown Anki deck respects your time.
Unlike the JackSparrow deck, which is famous for its "basic" card style (question on the front, paragraph on the back), MileDown uses Cloze deletions.
You’ve seen these before. It’s basically "fill in the blank." For example: "The [{{c1::medulla oblongata}}] is responsible for regulating breathing and heart rate."
Cloze deletions are fast. You can burn through 100 cards in 20 minutes once you get into a rhythm. This speed is a double-edged sword, though. Some critics argue it leads to "pattern recognition" rather than true conceptual understanding. You might recognize the card by the picture of the brain rather than actually knowing the physiology.
To combat this, you have to be honest with yourself. If you’re just clicking "Good" because you remembered the word starts with an 'M', you’re failing the exam before you even take it. Real mastery comes from explaining why that answer is correct before you flip the card.
Comparing MileDown to the New Kids on the Block
The MCAT prep world is competitive. Everyone is looking for that extra 1%.
Lately, the AnKing MCAT deck has taken over as the "ultimate" resource. It’s essentially a massive overhaul of MileDown, adding thousands of cards and tags for different textbooks. Is it better? Maybe. It’s certainly more detailed. But it’s also overwhelming.
If you have six months to study, go for AnKing. If you have three months and a full-time job? MileDown is the move.
Then there’s the JackSparrow deck. This one is for the masochists. It’s incredibly dense and requires a deep level of active recall. It’s great for high-scorers who want to ensure there are zero gaps in their knowledge, but it’s a slog. MileDown feels like a sprint; JackSparrow feels like a trek through mud.
Most people find that MileDown hits the "sweet spot" of the Pareto Principle—80% of the results come from 20% of the effort. It covers the high-yield topics that appear on almost every exam. It won’t teach you the ultra-niche Physics equation that appears once every three years, but it will make sure you never miss a question on Amino Acids or the Krebs Cycle.
How to Actually Use This Deck Without Losing Your Mind
Downloading the deck is the easy part. Sticking with it is the hard part.
Anki is based on Spaced Repetition Systems (SRS). If you miss a day, the cards pile up. If you miss a week, you’re looking at a mountain of 1,000+ reviews that will make you want to throw your laptop out a window.
- Start early. Don't wait until your "dedicated study period." Start doing 20 new cards a day during your semester.
- Suspend everything. Don't try to learn all 2,900 cards at once. "Suspend" the entire deck and only "unsuspend" cards that correlate with the chapters you just read in your review books.
- Use the Tags. MileDown is excellently tagged. You can filter by subject or even by Kaplan chapter. This is the secret to staying organized.
- Customization is key. If a card doesn't make sense to you, change it. Add your own mnemonics. Delete a graphic that confuses you. The deck should be a living document that evolves as you learn.
Honestly, the biggest mistake people make is treating the MileDown Anki deck as their primary learning source. It's not. It is a review source. If you don't understand the underlying chemistry of a titration, memorizing a flashcard about the equivalence point won't help you when the AAMC throws a "curveball" passage at you.
The P/S Section: Where MileDown Truly Shines
If there is one area where this deck is undisputed, it’s Psychology and Sociology (P/S).
P/S is often called the "vocabulary section" of the MCAT. If you know the terms, you get the points. MileDown’s P/S cards are largely based on the famous "300-page Khan Academy Document."
By the time you finish the P/S sub-deck, you’ll be able to distinguish between Cognitive Dissonance and Self-Serving Bias in your sleep. Many students report jump-starting their P/S score from a 125 to a 129 just by grinding these cards for a month. It’s the closest thing to a "cheat code" in the premed world.
Potential Pitfalls and Limitations
Nothing is perfect. Not even a legendary Reddit deck.
The biggest gripe with MileDown is the Physics section. Physics on the MCAT is less about memorizing formulas and more about unit manipulation and conceptual application. MileDown gives you the formulas, but it doesn't always teach you how to use them in the context of a complex passage.
Also, some of the Biochemistry cards are a bit light. The AAMC has been leaning harder into experimental design and data interpretation lately. A flashcard can tell you what a Northern Blot is, but it won't teach you how to interpret a messy graph from a research paper.
You have to supplement. Use UWorld for practice questions. Use the AAMC official materials for the "logic" of the test. The MileDown Anki deck builds the foundation, but practice questions build the house.

Actionable Steps to Start Today
If you’re ready to dive in, don’t overthink it.
First, download the Anki app on your computer. It’s free. Then, head over to the r/Mcat sidebar or search for the original MileDown Reddit thread to find the download link.
Once you import the file, go into the settings. Set your "New Cards/Day" to something manageable—maybe 30 to 50. If you go too high, your reviews will become an unmanageable beast within two weeks.
Next, install the "Hierarchical Tags" add-on. This makes navigating the sub-decks much easier.
Finally, commit to the "Daily Minimum." Even if you don't study anything else that day, do your Anki reviews. Do them on the bus. Do them while waiting for your coffee. Do them between sets at the gym. Consistency is the only thing that matters with the MileDown Anki deck. If you stay consistent, the MCAT becomes a test of what you know, rather than a test of what you’ve forgotten.
Next Steps for Your MCAT Journey
- Audit your schedule: Determine exactly how many weeks you have until your test date and divide the 2,900 cards by that number to find your daily target.
- Sync to mobile: Download the AnkiWeb app (it's paid on iOS but worth every penny) so you can knock out reviews during "dead time" throughout your day.
- Integrate with practice: After every practice full-length exam, create your own custom cards for the questions you missed and tag them under a "Missed Questions" deck alongside your MileDown cards.
