JudiciaryPlus: AI Study Platform for Law Exam Prep

JudiciaryPlus is an AI-assisted study platform for judiciary and law exam preparation. A student picks their exam and syllabus, then plans, studies, practises and revises in one account, with an AI tutor that answers from legal sources rather than from memory.

Law exam preparation is spread across PDFs, notes, question papers and generic chatbots that can state the law confidently and wrongly. Students need one place that keeps their own record, focuses practice on weak areas and grounds AI answers in real statutes and judgments.

Independent product. I designed and built it end to end:

React front end, serverless API, Postgres database schema and AI integration

An automated test suite of more than 1,600 tests covering scheduling, revision, AI routing, admin permissions and data migrations

Separate production and staging environments with scripted release checks

AI tutor with streamed answers, grounded in retrieved statutes and verified judgments

Adaptive daily quizzes, model papers and timed mock exams with post-exam analysis

Syllabus management and a daily study planner built within a fixed study-hour budget

Adaptive revision queue ranked by recent mistakes, accuracy and due dates

Progress dashboard, reports, study calendar and a mistake book

Admin console with server-side role checks and an append-only audit log

Parent progress reports and per-account data isolated with row-level security

Reliable AI: each feature uses an ordered fallback chain across two AI providers, with a total time limit and health tracking, so one failing provider does not leave a student stuck.

Trustworthy scoring: revision priority and mastery are calculated by fixed rules from practice results. The AI model never decides them.

Secure admin: every admin action is checked on the server against a permission list, using the role stored in the database rather than anything sent by the browser.
