If you don't know how to structure cards to be effective, I highly recommend you read through the 20 rules of knowledge formatting https://supermemo.guru/wiki/20_rules_of_knowledge_formulatio...

I used Anki for 7 years without these rules and figured some of it out on my own.

After I used Anki / supermemo to learn these rules, I can learn at a much higher rate with less reviews and higher recall.
