Build Your Own Flashcard Study API

The "Flashcard Study API" project involves developing an API that allows users to create, manage, and use flashcards for studying. Users will be able to create decks of flashcards, each containing individual cards with questions and answers. The API will also support reviewing flashcards, tracking progress, and categorizing flashcards by topics or subjects. The goal is to provide developers with a tool to integrate flashcard-based study systems into web or mobile applications for educational or personal use.

Detailed Description

Flashcards are a widely used study tool that helps learners remember information through active recall and spaced repetition. This project will build an API to facilitate the creation, management, and review of digital flashcards. Users will be able to create and organize their flashcards into decks, categorize them by subjects or topics, and track their progress as they study. The API will also support features like marking cards as "known" or "unknown" and generating statistics to track study performance.

Here’s a detailed look at how users will interact with the Flashcard Study API:

1. Deck Management:

   • Create Decks: Users can create a deck of flashcards, which represents a collection of cards for a specific topic or subject (e.g., "Biology Chapter 1").

   • Edit Decks: Users can update the deck’s title, description, and other metadata.

   • Delete Decks: Users can delete a deck and all associated flashcards.

2. Flashcard Management:

   • Create Flashcards: Users can create flashcards by specifying a question (or prompt) and an answer for each card. Cards are added to specific decks.

   • Edit Flashcards: Users can update the content of individual flashcards.

   • Delete Flashcards: Users can delete flashcards from a deck.

3. Study Mode:

   • Flashcard Review: Users can review flashcards in a deck. Each card will display the question, and users can choose to reveal the answer.

   • Mark as Known/Unknown: Users can mark a card as "known" (answered correctly) or "unknown" (answered incorrectly).

   • Progress Tracking: The API will track the user's progress in studying a deck (e.g., the percentage of cards marked as known).

4. Categorization and Tags:

   • Subjects/Topics: Users can organize decks by subject or topic (e.g., Math, History, Science).

   • Tags: Users can assign tags to individual flashcards for easier organization and searchability (e.g., "Vocabulary," "Key Concepts").

5. Optional Features:

   • Spaced Repetition: Implement a spaced repetition system to remind users to review flashcards at optimal intervals.

   • Sharing Decks: Allow users to share decks with other users or make them publicly available for community use.

Example Usage

Imagine a student named John who is preparing for his biology exam. John uses the Flashcard Study API to create a deck called "Biology Chapter 1" and adds flashcards with questions about key concepts. He uses the API to study the deck and marks each card as "known" or "unknown." As John studies, the API tracks his progress and generates statistics showing that he has mastered 75% of the deck.

• Create Flashcards: A user adds questions and answers to a deck by creating new flashcards.

• Study Flashcards: A user reviews the flashcards in a deck, marking them as known or unknown.

• View Progress: A user views their progress in studying a deck (e.g., the percentage of cards they have mastered).

6. User Stories

1. As a user, I want to create flashcard decks for different subjects so that I can organize my study materials.

2. As a user, I want to add flashcards with questions and answers to my decks so that I can study key concepts.

3. As a user, I want to mark flashcards as known or unknown so that I can track my progress during study sessions.
