Progress proof
See whether daily Chemistry practice is turning into stronger outcomes, better retrieval, and readiness for board-style sections.
Parent buyer path for CBSE Class XII Chemistry families
Weekly Parent Progress Update & 7-Day Mistake-Repair Plan
See whether Chemistry practice is turning into board readiness.
PrepAI gives parents a calm proof layer: progress proof, study consistency, mistake repair, source verification, and mock readiness for the Class XII Chemistry daily study loop.
The parent path is built for trust without overreach. You see habits, weak outcomes, repair evidence, and readiness signals while the student keeps control of their work.

Trust constraints
PrepAI shows how the study loop is constrained before asking for trust.
Source-safe
Official sources guide structure and coordinates; PrepAI content stays coordinate-based.
Deterministic tools
Chemistry calculators and paper compilation use local rules, not runtime AI guesses.
Answer-masked
Answers, explanations, and rubrics stay locked until the student commits a response.
Review-gated
Questions must pass content review before DPP, practice, assignment, or mock use.
Secure rendering
Formula rendering uses KaTeX with trust:false and unsafe math commands blocked.
What parents can verify
The parent path turns PrepAI from a black-box practice app into a visible study operating layer between tuition, school, and exam day.
Study consistency
Track attendance, streaks, due reviews, and daily DPP completion so the habit is visible before exam pressure spikes.
Mistake repair
Wrong attempts stay visible as repair work until the student succeeds through spaced retrieval instead of just reading feedback once.
Source verification
Question IDs can point to approved coordinate metadata, review state, and hash status without copying source passages into the product.
Mock readiness
Parents see whether the student is ready for official-format sections, timing pressure, and the next three repair actions.

Trust rules for the parent surface
Parents need enough proof to trust the study plan, but not access that weakens active recall or exposes student-private work. This route stays buyer-safe, source-safe, and payment-safe.
Parent views stay read-only.
Progress is summarized at habit, outcome, and readiness level.
Content reaches students only after review-gated approval.
Payment remains fail-closed while provider state is UNKNOWN.
Start with a parent-safe account path.
Signup opens the safe parent workflow. Paid access stays governed by the fail-closed plan state until provider evidence is verified.
