Bubble sheets, scanned and scored in bulk.
Overview
- Bubble sheets, scanned and scored in bulk.
Generate OMR sheets matched to your paper, print them, then bulk-scan on any office scanner — bubble detection auto-maps to your answer key, with version shuffling to deter copying.
- Generate & print sheets
- OMR sheets with alignment marks, matched to your question paper — print and photocopy for the whole hall.
- Bulk scan & auto-score
- Upload a batch of scans from any scanner; the system detects bubbles and maps them to the answer key automatically.
- Version shuffling
- Shuffle question/option order across versions to deter copying in large halls — each version scores against its own key.
- Zero student devices required — ideal for high-volume MCQ mocks, JEE/NEET style.
- OMR sheet generation with alignment marks
- Bulk scan upload + automatic bubble detection
- Answer-key auto-mapping
- Offline exam analytics
- Works with any office scanner
- What scanner do I need?
- Any standard office scanner or even phone photos at sufficient resolution — no special hardware.
- How many sheets can I scan at once?
- Bulk upload is built for hundreds of sheets per batch.
- Does it handle multiple paper versions?
- Yes — version shuffling generates distinct sheets, each scored against its own key.

Design a print-ready bubble sheet in a guided wizard
Start from the paper or online exam you already built, pick a CBSE, NEET, JEE Main or CAT preset, and tune the sheet until it matches your hall — roll-number grid from six to twelve digits, three to five options per question, two to five columns, and bubble size and shape to suit the pencils your students actually bring. A four-step wizard walks you from source to layout to marking to review, so nothing is left to a template you have to remember. Every sheet prints with alignment marks on A4 or Legal, carries your institution branding, and can include a QR code that ties it to one named student.
- Source questions from any Paper Canva paper or online exam
- CBSE, NEET, JEE Main, CAT and custom presets
- Roll-number digits, 3–5 options, 2–5 columns, bubble size and shape
- Sections with per-section marks and negative marking
- Institution branding and an optional QR code on every sheet
A stack of sheets becomes a marksheet in one upload
Print per-student QR sheets or a photocopy-friendly blank template, run the exam, then bulk-upload the scans in batches from any office scanner — or photograph them with a phone. Bubble detection reads every response with a fill ratio and a confidence score, auto-detects roll numbers from the grid, and evaluates the whole batch against the answer key. Marks it is unsure about go to a review queue rather than being silently mis-scored, and a single action-centre tile evaluates every unprocessed sheet at once when the last stack comes in.
- Bulk upload in batches — works with any office scanner or phone photos
- Automatic bubble detection with per-bubble fill-ratio and confidence
- Ambiguous marks land in a review queue instead of silently mis-scoring
- Version shuffling — 2–4 shuffled versions, each scored against its own key
- One action centre tile evaluates every unprocessed sheet at once
Bubble marks that land on chapters, not just totals
Because the sheets are generated from papers you already tagged, every scored bubble maps back to a chapter and a topic rather than stopping at a total out of eighty. Subject analytics rolls that up by board, class and subject, so a chapter the whole batch fumbled is visible the same evening the sheets are scanned — not at the end of term when the syllabus has moved on. Every student gets their own result view, marks export to Excel for whatever the office does next, and OMR results sit in the same analytics as your online exams and AI-graded answer sheets, so one weak chapter shows up once instead of in three separate reports.
- Chapter and topic-wise performance from a paper exam
- Per-student results with a student-facing view
- Marks export to Excel
- OMR results sit in the same analytics as online and answer-sheet exams
Sunday mock for 500 students, scored by Monday morning
Print two to four shuffled versions with a QR-identified sheet per student, then run the mock in halls with no devices and no logins. The stack goes through the office scanner in batches, each version scored against its own key with negative marking applied. By Monday you publish chapter-wise results for the whole batch, so the week’s revision plan is decided by data.
- Two to four shuffled versions, each scored against its own answer key
- Per-student QR sheets, so a scan identifies itself without a roll-number grid
- Negative marking and per-section marks configured exactly to the pattern
- Bulk upload in batches from any office scanner, no dedicated hardware
- Ambiguous marks queue for a human rather than costing a student marks
- Chapter-wise results across the whole batch, ready before the week starts
Objective assessments without a computer lab
Objective assessment usually stalls on hardware — not enough machines, and a lab timetable that cannot absorb six sections in an afternoon. Here students need a pencil. The school prints sheets from the term paper it already built, runs the test in ordinary classrooms, and scans the pile on the office copier. Only genuinely ambiguous bubbles reach a teacher.
- Students need only a pencil — no devices, logins or bandwidth
- Sheets generate from the term paper the school already built
- Photocopy-friendly blank template when the roster is not ready yet
- Automatic bubble detection with fill ratio and confidence per bubble
- Marks land in the same gradebook as online exams and answer sheets
- Roll-number grid from six to twelve digits, three to five options, two to five columns
- Institution branding and alignment marks on every printed sheet
Class test on paper, analytics on screen
No scanner, no lab, no IT ticket. Photograph the sheets with a phone at the end of the period, upload the batch and hit evaluate-all. An evening of ticking bubbles becomes about ten minutes — and you get the part never worth doing by hand: topic-wise weak spots, and per-student results for the parent meeting.
- Phone photographs work as well as a scanner for a single class
- One action-centre tile evaluates every unprocessed sheet at once
- Chapter and topic-wise performance from a paper exam
- Per-student results with a student-facing view for the parent meeting
- Marks export to Excel for whatever the office does next
- Set the marking scheme once, negative marking included, and the next test reuses it
- Sheets build from any Paper Canva paper or online exam you already made
- Results sit beside online-exam and answer-sheet marks in one analytics rollup
