Daily review
422 cards across four tracks, in one queue ordered by what you are closest to forgetting. Grade yourself, and each card reschedules itself - a few minutes a day beats a weekend of cramming.
How the scheduling works
One queue, every track
System Design, AI/ML, Python full-stack and the CS syllabus arrive in a single session instead of four separate decks.
Scheduled, not shuffled
Get a card right and it comes back in 1 day, then 3, then further out each time. Miss it and it returns the same day.
Your mistakes feed it
Miss a question in any quiz - or the question of the day - and it joins this queue automatically, scheduled like any other card.
Drill a single track
The queue mixes everything. To focus on one subject, open its deck - grades there feed the same schedule.

A nudge on the days you forget
One short weekly email - the week's best question and what shipped. The queue does the rest.
