AWS Cert Flashcards
I was studying for the AWS Certified Solutions Architect Associate Exam, and I found that studying the question set is very inefficient. Therefore, I quickly built a flashcard web app to help me study while commuting and to revisit incorrect questions. Deployed at donchong2000.github.io/flashcard.
Features
Practice Modes

All questions: cycle through the full bank

Progress Tracking
Answers are stored in localStorage, so correct/incorrect history persists across sessions. You can filter to show only questions you got wrong or ones you've bookmarked for review.

Data Portability
Progress can be exported as JSON and re-imported, making it easy to back up. Answer history is stored as a hex bitmap, keeping the exported data compact and human-readable.
Offline / PWA
The app is installable and functions fully offline, useful for studying on the go without a connection.
Adding Question Banks
New exam datasets can be contributed by placing a JSON file in the data/ directory following the schema (questions, options, correct answers, community votes, discussions). The build process picks them up automatically.
