Your question bank and progress sync across all your devices through your account.
Local, offline question bank. Nothing leaves this file. Progress is saved in this browser — use Export regularly to keep a backup.
Lifetime performance across all sessions in this browser.
Self-contained export of new incorrect or flagged questions (id · status · stem · correct answer · explanation) for review. Already-dumped questions are skipped automatically. Copy first, then mark as dumped.
Back up your progress, or load real questions (e.g. your Raja Tier-1 set) into the bank.
Renames every question in that category. Progress, flags, stats and the dump log are keyed to each question's id, so nothing is lost.
Paste an array of question objects. Merge adds new ones (matching id is replaced); Replace bank wipes existing questions first. Progress is keyed by id, so keep ids stable.
