I understand that SRS programs like Anki is for review what you learn, not to learn the card completely new. However, for learners who require to learn a lot of new words (to pass a test for example), having them showing on each day to learn is extremely convenience.
To fully optimized the learning curve, each card needs to be personalized. However, actually personalizing 1000 words consumes a lot of time and energy. I think that there are type of information that don't need your customization, so I can save time by using pre-made information, like a shared deck or getting data from a source by scripting.
Which type of information that serve better when they are personalized, and which don't? How to personalize a vocabulary flashcard deck without spending too much time on it?
