Hello. I apologize if this has been asked before I tried searching but did not find anything. I added anking to my existing miles down deck and Iām wondering if I need to be worried about any duplicate cards or cards from the old deck that carried over that might be out of date. I also have two Orgo and two gen chem decks and Iām confused on how these duplicates happened.

You donāt need to panic, but there are a few things to be careful about when combining decks like this.
1. Duplicates between Milesdown and AnKing MCAT
Milesdown and the AnKing MCAT deck both cover similar content, so itās normal to end up with:
- Two cards testing the same fact but:
- Different wording
- Different note type
- Different tags
Anki/AnkiHub wonāt automatically delete or merge those for you. You have three main options:
- Keep both and suspend as you go
- As you study, if you see two cards that feel truly redundant,
Edit ā Suspendone of them (pressJon desktop, or Suspend from the card menu on mobile).
- As you study, if you see two cards that feel truly redundant,
- Pick a āprimaryā deck
- Many people choose AnKing MCAT as their main updatable deck (via AnkiHub) and:
- Keep Milesdown for now
- Gradually suspend Milesdown cards that overlap with AnKing MCAT
- Many people choose AnKing MCAT as their main updatable deck (via AnkiHub) and:
- Turn off AnkiHub updates for Milesdown-style cards
- Subscribe/sync only to AnKing MCAT via AnkiHub
- Keep other decks as ālocalā (not on AnkiHub) to avoid future conflicts
In short: yes, duplicates are expected; no, they donāt automatically cause problems. Youāll just see more cards unless you suspend the ones you donāt want.
2. Why you have two Orgo / two Gen Chem decks
From the screenshot, it looks like you have something like:
MilesDown's MCAT Decks ā General ChemistryAnKing MCAT Notes Types ā General Chemistry(or similar under the AnKing structure)
Common reasons this happens:
- You imported Milesdown first (which created its own subdecks).
- Then you imported AnKing MCAT, which also has its own
General ChemistryandOrganic Chemistrysubdecks. - Anki treats those as separate because they live in different parent decks / were imported from different packages.
This is completely normal. They are just two different sources for the same subject.
3. Are any cards āout of dateā or ācarried over wrongā?
- Adding AnKing does not modify your Milesdown cards.
- AnkiHub updates will only affect cards that:
- Use the AnKing MCAT note types, and
- Are part of a deck that is subscribed to the AnkiHub AnKing MCAT deck.
So your old Milesdown cards stay as they are. If something is outdated, it will remain that way unless you manually edit/suspend it, or switch to the updated AnKing version.
4. What Iād recommend next (practical plan)
On desktop (if possible; itās much easier than on mobile):
- Choose your main deck
- If you want upātoādate, communityāmaintained content, use AnKing MCAT as your primary longāterm deck.
- Rename decks for clarity (optional but helpful)
- E.g.
MilesDown ā General ChemistryAnKing ā General Chemistry
- This helps you quickly see which deck a card belongs to.
- E.g.
- As you study, prune duplicates
- When you see near-identical cards:
- Keep the better one (often AnKing),
- Suspend the other.
- When you see near-identical cards:
- Donāt delete decks yet
- Until youāre comfortable, just suspend cards rather than deleting. You can always unsuspend later.
5. If you want more tailored help
If you can, post:
- A screenshot from Anki desktop ā Browse, filtered to:
Deck: "MilesDown's MCAT..."Deck: "AnKing MCAT..."
- And let us know:
- Which deck you prefer (Milesdown vs AnKing MCAT),
- Whether youāre already subscribed to the AnKing MCAT deck on AnkiHub.
Then we can walk you stepābyāstep through:
- How to safely keep AnKing MCAT up to date via AnkiHub, and
- How to handle or reduce the existing duplicates in a way that wonāt break your collection.
Hello,
I would be happy to help. ![]()
Itās hard to say with any certainty, but Iāll lay out the basic ideas:
- Miledown has existed in various forms across the internet for years. Itās hard to know, with any confidence, which version you have and which changes have been made to that deck.
- Most versions of Miledown will be compatible with the AnKing MCAT deck, which means that the notes share IDās and duplicates wonāt be made. Notes that share a lineage will be updated in place
So:
- If the notes share a lineage, and are present in both decks, they will be updated in place.
- If there are new cards in the AnKing MCAT deck they will be added.
- If there are old cards from Miledown that do not share a lineage, they will remain (AnkiHub does not delete anything in your collection).
Itās hard to know, as it could be for a hundred reasons. But, it is easily enough fixed; you can simply move cards around and organize your local collection as you see fit
This tutorial uses the AnKing Step deck as an example, but can walk you through how to move cards around so that you can reorganize your local collection to your preferences: How to move AnKing cards to their own deck
Please let me know if that answers your question, and if thereās anything else I can help with. ![]()
