Synced my MCAT Anking deck (older version) with the newer one, but now two of some of the topic decks like Physics and Math, General Chemistry and Organic chemistry

How can I fix this, I thought I did the sync correctly but apparently not, there was an option while I was syncing that said delete or something, but I didn’t click it because I didnt want to delete my progress, if anyone knows please help!

Hello,

Where did you install the original MCAT deck?

When installing the AnkiHub version of the MCAT deck, all cards should overwrite with the new cards from AnkiHub if you are using a previous version of the MCAT deck

Are they duplicate cards?

If they are not duplicate cards, you can move all the cards in the duplicate decks to the original ones

I believe the total card count is accurate of 6257 cards, so i believe my cards are not duplicated, but if you could confirm that would be great. I am still not 100% comfortable with Anki, so how can I more all the cards in the duplicate decks to the original ones, step-by-step?

Yes that is around the same number of cards I have so they are not duplicated.

To move cards, find the deck that you want to move by going to browse → on the left hand side click on deck → select the deck.

After selecting the deck, click on a card and Ctrl + A to select all the cards → right click → change deck → select the deck you want all those cards to go into
