The story
412 sheets. One teacher. Tuesday night, then the same test on Wednesday.
The evening pile. What it costs, and what changes.
One continuous scene. A teacher checks a pile by hand, the camera pulls back to the institute and to the student waiting on it, and then the pen changes.Scroll slowly. The scene moves with your scroll, so you can stop, go back and look.

Sheet 1 of 412.
Hetal ma'am starts the pile the way every teacher does: one sheet, one red pen, three minutes if nothing goes wrong.
Tuesday · 9:55 pm
Three minutes each. Four hundred and twelve of them.
Twenty hours of checking, and not one of them falls inside the teaching day. Somewhere around sheet 200 the marks start to drift.

Wednesday · 4:14 pm · the marking scheme
Before the first mark, the scheme. Once.
She uploads the model answer. Vidya Vault splits it into the points that earn marks; she confirms or edits the split once per question, and every sheet after that is marked the same way.
Wednesday · 4:20 pm · read and mark
4,944 answers. Three languages.
Every page is split question by question: handwriting, working steps, numericals, in Gujarati, Hindi or English. Each answer gets a proposed mark against her scheme and an examiner's note, and waits for her.
Wednesday · 4:21 pm → 6:40 pm · review
Every mark proposed. Every mark still hers.
Agree, and approve in one tap. Disagree, change the mark; the note updates with her. Nothing reaches a student before this.
Wednesday · 6:40 pm
Results out at 6:40. Dinner at 8.
Twenty hours of checking became two hours of reviewing. Every mark is still a teacher's; only the slow part is gone.
Checking time · one test
20 h2 h
Reviewing, not checking. Every mark is still a teacher's; one of them she changed herself.
The institute · 7:05 pm
One scheme. Every batch, every branch, every teacher.
The scheme was confirmed once and applied to every sheet, so the same answer earns the same mark in every room. Results in the same week, and a report for every parent.

Questions
Asked by every owner so far.
Anything else, ask on the call. We book one within a working day of your pilot request.
Which languages can it read?
Handwritten answers in Gujarati, Hindi or English, including working steps and numericals. Long answers, numericals and MCQs in board pattern are all read the same way.
Does the AI decide the marks?
No. Every mark is a proposal with an examiner's note. A teacher approves it or changes it in one tap, and nothing reaches a student until that has happened.
What do students and parents get?
Every answer comes back with what earned marks, what did not, and the correct working, two days after the test. Parents get the same report on their phone the same evening, sent once by the institute.
How does it learn our marking scheme?
Upload the model answer. Vidya Vault splits it into the key points and steps that earn marks; your teacher confirms or edits that split once per question, and every sheet after that is marked the same way. Step marks for numericals and your institute's partial-credit practice are part of the scheme.
What do we need to start?
A phone with the Vidya Vault app on iOS or Android, and your model answers. No new hardware and no retraining: teachers scan the stack the way they would photograph it.
What does the pilot include?
One full exam cycle, free. We set the scheme up with your teachers, they review the marks as usual, and you judge the results before deciding anything.
Whose data is it?
Your institute's. Answer sheets, schemes and marks stay yours. Ask us about storage and retention before the pilot starts and you will get the answer in writing; the privacy policy is linked in the footer.
