The architecture in action

Build a 10-question practice set in seconds.

Choose a subject and filters. The site randomly selects existing questions from a 1,000-question library split across five subject JSON files. Students practice with stored content—no AI model is called to generate questions or solutions on demand.

“Cache” can mean different things: Here, questions are pre-generated once and saved persistently in JSON files—the bank is the durable source of truth, reused for every test. Browser/edge caching can also keep copies of those static files closer to visitors. An AI prompt cache may discount repeated prompt tokens, but it still involves an AI API request. This demo makes no model/API calls at practice time; it simply selects already-saved questions.

Demo content: 1,000 original template-generated AMC 8-inspired examples, not official AMC questions. Numeric variations are produced from a set of reusable problem templates to demonstrate the architecture—not to represent a finished contest-prep curriculum. The bank has programmatic structure/answer-key checks; all questions and explanations require qualified human review before public educational use.
