v1.3.0 — Custom Multi-Chapter Test Builder

What's New

Features

• Custom Test Builder — Students can now build a personalised test by selecting chapters across multiple subjects in a 3-step wizard:
  • Step 1 — Select Board & Grade
  • Step 2 — Browse subjects, add chapters to a basket (removable chips); freely switch subjects to pick across subjects
  • Step 3 — Review AI-generated chapter summaries before starting the test
• Multi-Chapter Question Merging — Questions from all selected chapters are merged by mark-band: Section A (1-mark) → Section B (3-mark) → Section C (5-mark), shuffled within each section
• Chapter Summaries — AI-generated 3–5 sentence summaries for each chapter, cached after first generation (GET /api/chapter-summary/<id>)
• New API Endpoint — POST /api/start-custom-test accepts multiple chapter IDs and builds a combined test session

Bug Fixes

• Fixed 500 error on Admin → Students tab when a student record had a NULL created_at timestamp
