Institute and school papers sit ungraded in WhatsApp forwards and plastic sleeves — parents pay ₹3,000–₹8,000/month for tuition and test series but lack topic-level feedback until report cards land at 52%.
Bottom line
Upload PDF or flat photo at /custom → solve online → graded report feeds PIN dashboard. Tag subject and chapter before generate. Sunday: one misconception from the report — not a folder audit.

Three perspectives
Parent
Saturday coaching returns a mock total on SMS — you still do not know if Electricity or quadratics caused the drop.
Do this
Photograph the paper flat Sunday morning; teen solves before Monday school. Review one flagged topic on the PIN dashboard.
Avoid
Stacking institute papers unattempted until pre-board panic — volume without feedback trains false confidence.
Student
You attempt the coaching mock once, lose the paper, and repeat the same mistakes on the next institute test.
Do this
Upload within 48 hours while mistakes are fresh. Re-solve wrong items with hints off after grading.
Avoid
Crumpled phone photos in yellow kitchen light — OCR skips half the sub-parts.
Teacher
Homework is paper-based; you cannot mark 40 uploads nightly.
Do this
Encourage Custom Test upload for weak-topic tagging — student brings graded report to doubt period.
Avoid
Treating upload as cheating — retrieval on paid papers is practice, not malpractice.

Grade the paper you already paid for
Custom Test closes the loop on institute and school spend. Most Indian families already buy the paper — they lack the per-question feedback loop that moves marks. Upload converts a static PDF into the same graded report card flow as generated worksheets.
Pair uploads with the parent-dashboard-weekly-checklist ritual: Sunday PIN review of one misconception from the latest custom test, not a surveillance pass through every answer line.
Folder archive vs graded report
Before upload: parents know a total percent from coaching SMS; students guess retry chapters; the same errors repeat on the next mock. After upload: topic mastery tags populate the dashboard, wrong items become a 48-hour retry queue, and Sunday check-ins shift from "Did you attempt it?" to "What did the report flag?"
The before/after difference is not more paper — it is item-level signal on paper you already own. That is why metro parents paying for test series still feel blind until report cards.
Photo quality is the parent superpower
Students rush uploads; parents who spend five minutes on a flat daylight photo save twenty minutes of OCR frustration. Contrast surface, parallel phone angle, and full-page capture including sub-part margins are the three fixes that rescue most failed extractions.
When handwriting is too dense for OCR, fall back to a generated 20-mark worksheet on the same chapter — the weak-topic tag still lands on the dashboard either way.
If this sounds like you
Situation: OCR extracted fewer questions than the paper
Action: Retake flat photo per checklist or generate 20-mark worksheet on same topic
Quality gate beats forcing a partial solve.
Situation: JEE/NEET Saturday institute mock
Action: Upload Sunday; weekday 20-mark drill on weakest PCM/Biology chapter from report
Maps institute spend to home retrieval grid same week.
Situation: Parent sees 47% total but no topic breakdown
Action: Custom test upload + Sunday PIN review of one misconception
OCR quality varies with handwriting density and lighting — retake beats guessing.
AI rubric is formative practice feedback — not official CBSE or ICSE board marking.

Who this is for
Parents paying for tuition who still lack graded evidence on institute papers
Students with stacks of unsolved school unit tests before pre-boards
JEE/NEET aspirants re-drilling coaching mocks at home
Families in metro and tier-2 cities who already spend on test series but never see item-level analysis
Custom test vs worksheet generate
A generated worksheet creates new questions from your syllabus topic. Custom Test extracts questions from a paper you already have — school unit test, coaching mock, or tuition homework sheet. Both paths grade online and feed the same weak-topic dashboard. Custom Test is for papers you paid for but never got per-question feedback on.

Sunday check-in is one misconception from the report card
In most Indian households, the tuition fee covers the paper — not the feedback loop. A Class 10 parent in Pune might get a 47% total on Saturday's institute test and still not know whether Electricity or Carbon Compounds caused the drop. Custom Test closes that gap without buying another test series.
Photo quality checklist
Lay the paper flat on a contrasting surface — white sheet on dark table or vice versa.
Shoot in daylight or under a desk lamp; avoid yellow ceiling light that washes out pencil marks.
Hold the phone parallel to the page — no diagonal angle that skews question numbers.
Capture full pages including margins where sub-parts (a), (b), (c) often live.
Wipe the camera lens; blur from a smudged lens is the most common parent-upload failure.
If the paper is double-sided, photograph each page separately — do not fold to fit one frame.
For coaching PDFs, upload the file directly instead of photographing a laptop screen.
After upload, confirm extracted question count matches your paper before starting the solve.

Four-week upload habit for families
Week 1: Upload one school unit test per subject (Maths, Science, English). Solve within 48 hours of upload while memory is fresh. Parent runs a 15-minute Sunday PIN review on one misconception only.
Week 2: Add the latest institute or tuition mock. Compare weak topics on the dashboard — do they match what coaching reported verbally? Retry the lowest-mastery chapter with a generated 20-mark worksheet.
Week 3: Introduce a second attempt on questions missed in Week 2 uploads. Students re-solve wrong items in Custom Test with hints off. Parents stop asking "Did you study?" and ask "Which topic did the report flag?"
Week 4: Before pre-boards, upload only papers from the last 14 days. Stack older mocks only if the weak topic still shows below 60% mastery. Pair with parent-dashboard-weekly-checklist ritual every Sunday.
JEE/NEET coaching paper workflow
Upload Saturday institute mock on Sunday morning. Student solves online Monday evening. Wednesday: 20-mark topic drill on the weakest PCM or Biology chapter from the graded report. This mirrors the jee-neet-weekly-drill-routine without waiting for the next batch test.
When OCR struggles
Heavily handwritten margins, dark pencil on grey paper, or crumpled sheets reduce extraction quality. Re-scan flat in daylight or generate a fresh 20-mark worksheet on the same topic instead of fighting a bad photo.
Parents: Sunday upload ritual
After Saturday tuition or institute tests, spend five minutes photographing the paper flat while dinner is on the stove. Upload Sunday morning. Your teen solves before Monday school — you review one misconception on the PIN dashboard, not every answer line.
Parent line: Say: "I am not checking every step. Upload Saturday's paper Sunday and show me one topic the report flagged." That sentence replaces an hour of hovering.
Student line: Before you toss the coaching paper into a folder, photograph it flat and upload — your future self needs the graded report before the next mock, not the crumpled original.
Honest limits
OCR may miss heavily handwritten or low-contrast scans — retake photo in daylight if extraction fails.
Custom test grading follows the same AI rubric as worksheets — not official board marking schemes.
Upload file URLs are restricted to Mingi storage domains — do not paste external links expecting them to grade.
Flat PDFs work best. Tag the subject and topic so weak-area tracking stays accurate.
Photograph flat in daylight or upload PDF — avoid curled pages.
Tag subject and topic before generate for accurate weak-area tracking.
Graded custom tests appear in activity history and parent dashboard.

Frequently asked questions
What file types does Custom Test accept?
PDF and common image formats uploaded through the Custom Test flow at /custom. Clear, flat photos work best for institute papers. Coaching PDFs should be uploaded directly rather than photographed from a screen.
Do parents see custom test results?
Yes, when the student account links a parent profile. Graded custom attempts appear on the PIN-gated dashboard with topic-level feedback — the same loop as generated worksheets.
Is uploaded content private?
Files stay in your Mingi account under Supabase RLS. Mingi does not sell children's data. Mingi is operated by Ingagenow Marketing Consultant LLP and is DPDPA 2023 aligned — see the dpdpa-compliant-learning-apps-parents guide for full compliance notes.
What if OCR extracts the wrong number of questions?
Retake the photo using the checklist above — flat surface, parallel phone, good lighting. If handwriting is too dense, generate a 20-mark worksheet on the same chapter topic instead. Question count scales with total marks via customTestQuestionCount().
