Manage your cards

• Create an unlimited number of dual card binders, with an unlimited number of dual cards.
• A dual card is a card with 2 sides. For each side, you can upload an image, and/or add text in plain text, markdown or HTML. You can choose to have swappable sides.
• Create an unlimited number of multi card binders, with an unlimited number of multi cards.
• A multi card is a card with 3 parts. The first part is for the question. You can upload an image, and/or add text in plain text, markdown or HTML. The second part is the multiple choice part. You can add 1 to 9 propositions with text (plain text, markdown or HTML). You set the correct propositions by clicking on the corresponding checkboxes. The third part is for an optional explanation of the answer. You can upload an image, and/or add text in plain text, markdown or HTML.
• In any binder, you can create dozens of card at once (either dual cards or multi cards).
• You can name and rename your binders. You can also name and rename your cards if you want to.

Assess your mastery

• Each card saves a mastery score.
• For dual cards: you indicate whether you master the card or not (2 options).
• For multi cards: we automatically detect if you got the right answer or not, based on the checkboxes you clicked and submitted.
• All these scores are saved and used by specific practice strategies that prioritize cards based on mastery scores.

Share your cards

• All of your cards and binders are private by default. No one else can see them.
• If you have credits, you can export or import your binders of cards via a CSV. It's simple way for Optileague users to share cards.

• You can tag your binders with 1 or several tags. You can target the binders to practice with by tag.
• You can set cards or binders to inactive, so that they are not used in your practice sessions.

  • Random cards.
