For coaching institutes
Admissions to answer keys. One platform.
VidhyaKosh Enterprise runs both halves of a coaching institute: the operations — admissions, batches, fees, attendance — and the academics — your question bank, your test series, and the analytics that come out of them.

An institute is two businesses wearing one name. There is the office — enquiries, admissions, batches, fees, attendance, salaries — and there is the teaching: papers, tests, results, and the question of who is quietly falling behind. Most institutes run the first on spreadsheets and the second on WhatsApp, and neither half can see the other.
VidhyaKosh Enterprise is one platform for both, so the batch that owes fees and the batch that is failing Rotational Motion are finally the same list of names.
One platform, two products
Take either on its own, or both together. Every module below carries its real status, so you can see what runs on day one and what you are joining early to shape — 8 are live today.

Running today — the same systems behind our public JEE and NEET practice site. Your papers can be in it this month.
A week, once it is all in one place
The two halves stop being two systems. This is the week they add up to — with the same status labels as above, so you can see which days work today.
Monday
Attendance goes in from the register on the teacher's phone, not a roll call pasted into a WhatsApp group at midnight.
Wednesday
The weekly mock opens at 18:00 and closes at 20:00. Answers stay sealed until it closes, so the evening batch learns nothing from the afternoon one.
Thursday
Reports are ready before class. The teacher walks in knowing the three chapters the batch lost most marks in, and which students guessed rather than knew.
Friday
The fee reminder list is six names long, and the front desk works from it instead of remembering.
Sunday
Next week's mock is last week's, cloned into a draft and edited — scheduled in a minute, not rebuilt from scratch.
Institute OS
The office half: who is enrolled, who turned up, who has paid, and who is teaching what.
In build Being built now with founding institutes. The order on this page is the order it ships in, and partners move it.
- One register, not six spreadsheets
- Students, teachers, batches and centres in one place, so a student's fees, attendance and test results are the same record instead of three different people's files.
- Enquiries that do not go cold
- Every walk-in and phone enquiry tracked from first call to admission, with who followed up and when — the thing a busy front desk loses first.
- Attendance both ways
- Students and faculty. Who is missing class this week is a question about learning; who took the class is a question about payroll. One register answers both.
- Fees without the ledger book
- Structures, instalments, collection and receipts, with a due list a receptionist can work from. We never take a percentage of what you collect.
- Timetables and payroll
- Scheduling that knows which teacher is free and which room is booked, and salaries that follow from the hours actually taught.
- Multi-centre from the start
- Designed for institutes running more than one address, because that is the point at which spreadsheets stop working entirely.
Your papers become a question bank
Send the archive — scans, photocopies, decades of it. What comes back is searchable, tagged and ready to build tests from.
- Mathematics survives the scan
- Formulas come through as real, searchable mathematics rather than pictures of mathematics — and each one is checked against the page it came from.
- Figures come along
- Diagrams, graphs and circuit drawings are lifted with their questions, including the multi-panel ones, and each is verified before it is kept.
- Dense papers stay in order
- A fifty-question paper with three subjects and sectional instructions comes out as fifty questions in the right sections, not a wall of text.
- Tagged to your syllabus
- Every question lands on a chapter and a subtopic — 1,767 of them across four subjects — so "twenty questions on Thermodynamics" is a search, not an afternoon.
- Answer keys are verified, not trusted
- Each answer is checked independently before publication. A key that does not hold up is flagged for a teacher rather than quietly served to a student.
- Duplicates are flagged, never deleted
- Questions repeated across your papers are surfaced for a person to rule on. Nothing is silently thrown away.
Which of the following oxides is amphoteric: Al2O3, SO2, MgO, P2O5?

The exam room
A real CBT room for your test series — scheduled, sealed and scored the way the actual exam is.
- Scheduled windows
- A test opens and closes exactly when you set it to. A student already mid-paper when the window shuts can still finish and submit — locked out of starting, never out of finishing.
- Sealed results
- Set a paper to reveal answers only after the window closes, so the batch that sits it at 6pm learns nothing from the batch that sat it at 4pm. This is what makes a weekly series mean something.
- The clock lives on the server
- Sectional timing is enforced server-side. A student's browser clock — fast, slow or tampered with — never decides whether a section is still open.
- Marking that matches the exam
- Per-type negative marking, frozen onto the paper when it is published so later edits never re-price an attempt — including JEE Advanced partial marking for multiple-correct questions.
- Shuffle without chaos
- Question and option order can shuffle per student, then freeze. A resumed attempt never renumbers the palette mid-exam.
- Autosave, resume, attempt caps
- Power cut mid-paper? The attempt resumes where it stopped. Cap attempts per student, and clone last week's mock into next week's draft in one step.
Q.5 A particle moves in a circle of radius r with constant speed. The magnitude of its average acceleration over half a revolution is…
An archive nobody can search is a cupboard. A test you cannot schedule is a photocopy. A report nobody reads before class is a spreadsheet.
Why we are building this
What teachers see
Reports that say what to fix next — and say nothing when the data is too thin to know.
- Silence over noise
- No verdict is drawn from a thin sample. If the data cannot support a claim about a weak chapter, the report stays quiet rather than guessing — a wrong insight costs a teacher more than a missing one.
- Three kinds of lost marks
- Marks lost to negative marking are a behaviour problem. Marks missed are a knowledge problem. They are counted separately and never merged, because they call for different fixes.
- Guessing and overthinking, defined
- A wrong answer given in well under the expected time is guessing; one that took over twice the expected time is overthinking. The definitions are printed with the numbers, not implied.
- Every insight quotes its number
- Insights come from fixed rules, not a language model. Each one cites the figure that triggered it — a claim a teacher cannot verify is not a claim worth making.
- Mistakes stay until fixed
- Every wrong answer is kept, grouped by chapter, until the student resolves it — and one click turns the unresolved pile into a fresh practice set.
Most marks lost in Rotational Motion: 9 of 12 wrong, at twice the usual time per question.
Four answers were given in under 20 seconds and all four were wrong — that is guessing, not a knowledge gap.
Control and trust
Roles, audit trails and answer-key hygiene, on by default.
- Roles, re-checked on every request
- A reviewer can moderate; only an admin can publish, upload or manage accounts. Permissions are read fresh on every request, so revoking access takes effect immediately — not when a token happens to expire.
- A year of audit trail
- Every privileged action records who did it, what changed, and the before and after — kept 365 days by default, with anything that looks like a password or token redacted before it is stored.
- Answer keys cannot leak
- What reaches a student mid-exam contains only what a student is allowed to see. Answers and explanations are not stripped out of it — they were never in it.
- Private by default
- Your bank and your tests start private. Publishing anything is an explicit, recorded act by a named account.
Founding institutes
Exam OS runs today. Institute OS is being built now, and the institutes that join at this stage decide what gets built first.
Start with the teaching
Your papers go in and your test series runs on Exam OS. This half works on day one, so the platform earns its place before anything is promised.
Shape the office half
You tell us which Institute OS module hurts most — the fee register, the enquiry list, the attendance sheet — and that is what gets built next.
Keep founding terms
Every module ships to founding partners as it lands, at the terms agreed at the start — and never a commission on your fee collection.
Questions institutes ask
Who owns our question bank?
You do. Papers you upload, and the bank built from them, are your institute's content. They stay private to you: nothing from your archive is published, shared or used to serve anyone else's students.
Which parts can we use from day one?
Exam OS in full -- your question bank, the CBT exam room, scheduled test series and student analytics. Institute OS is in build with founding partners, module by module, in the order shown on this page. Every module in the list above carries its real status, so you can see exactly where that line falls before you even talk to us.
Our papers are old photocopies. Will they work?
They are what the system is built for. Anything read with low confidence goes to a review queue where a person rules on it before it can reach a student. Bring your worst paper to the demo -- that is the honest test.
What does it cost?
There is no public price yet. Founding institutes agree pricing directly with us and keep those terms as the platform grows. We do not take a percentage of your fee collection, ever.
What do our students and staff need to run it?
A browser. The exam room, the dashboards and the console are web applications that work on ordinary computers and phones -- nothing to install, and an exam attempt survives a dropped connection or a closed tab.
Can we run our weekly test series on it now?
Yes. Scheduled open and close windows, results sealed until the window closes, attempt caps, and one-step cloning of last week's paper into next week's draft all work today.
See it on your own papers
Bring one of your institute's papers to the demo. We will run it through and hand you the result — then show you where Institute OS has got to.
- Thirty minutes, on a video call
- Your paper, processed while you watch
- Founding terms, discussed openly
