Does my progress save?

Yes — studied cards and ratings are stored in your browser's localStorage and persist between visits.

How does spaced repetition work?

Cards you rate as 'Hard' are assigned a higher priority weight and appear more often when the deck is sorted.

Can I study just one category?

Yes — use the category dropdown to filter to any single topic like Algorithms or System Design.

What modes are available?

Flashcard Flip (reveal answer on click), Multiple Choice (3 distractors from the same category), and Self-Rate (mark easy/hard after seeing the answer).
