I’ve been using Anki on and off for years for language learning but have most recently been using it to study for online uni courses.

Something that’s become evident, perhaps due to the varied nature of the content (vs. all language) is how much gravity card formatting has. In decks made by others I find myself frequently re-wording the answer sides of the cards which makes a noticeable difference in retention — answers that are succinct and flow nicely stick better.

So in short, I’d concur. Card format is important. If you find a card that feels awkward somehow don’t hesitate to rework it.
