What is MCQ correction by scanner?

MCQ correction by scanner automatically digitizes your paper copies and extracts student answers using OCR (optical character recognition) technology. No more manual data entry: scan, and the software does the rest.

Save precious time

With MCQ Corrector, turn hours of manual correction into minutes of scanning. Our OCR technology recognizes checked boxes with over 99% accuracy.

How does MCQ scanning work?

1

Create your MCQ

Generate your MCQ with standard checkboxes or use AMC format for optimal compatibility.

2

Print and distribute

Print your MCQs with barcodes or positioning markers to facilitate recognition.

3

Scan the copies

Use a standard scanner (300 DPI min.) or your smartphone to digitize the completed copies.

4

Automatic grading

Our OCR detects checked answers, compares with the answer key and generates grades instantly.

Scan with smartphone

No professional scanner? No problem! Our technology accepts photos taken with a smartphone. Just make sure you have good lighting and a sharp image (avoid shadows and blur).

Technical scan specifications

                     Recommended scan quality
                    Minimum resolution: 300 DPI (ideal: 600 DPI)
Format: PDF, JPEG, PNG, TIFF
Color: Black & white or grayscale (color accepted but heavier)
Contrast: Good contrast required (no major shadows)
Orientation: Portrait or landscape (automatic detection)

                

                     Common issues to avoid
                    Scan too light or too dark: Adjust your scanner's brightness settings
Folded or crumpled copies: Flatten sheets well before scanning
Major shadows: Use a flatbed scanner rather than a smartphone when shadows are present
Insufficient resolution: Make sure your scanner is set to at least 300 DPI
Cropped pages: Make sure the entire page is visible in the scan

                

Pro tip: For optimal smartphone scanning, use a dedicated app like "CamScanner" or "Adobe Scan" which automatically corrects perspective and improves contrast. Our help guide provides detailed instructions for each type of device.

Frequently asked questions about MCQ scanning

Can I scan my MCQs with any scanner?

Yes! Any scanner capable of producing images at 300 DPI minimum works perfectly. Standard desktop scanners, multifunction printers, and even smartphone scan apps are compatible. The important thing is to get a sharp image with good contrast.

What is the difference between AMC and your AI scanner?

AMC (Auto Multiple Choice) is an excellent open-source MCQ correction software by scan, but it requires a strict MCQ format. Our solution integrates the power of AMC while adding AI to recognize more flexible formats, automatically generate questions, and provide a modern and intuitive interface. You get the best of both worlds.

Does scanning work with partially handwritten copies?

Our OCR focuses on recognizing checked boxes for MCQs. If your students add handwritten annotations alongside, they do not interfere with detection. However, for handwritten open-ended questions, manual correction is still required (but you can annotate directly on our interface).

How long does processing take after scanning?

Processing is near-instant: count about 2-3 seconds per copy. For 100 copies, the full processing (recognition + correction + statistics) generally takes less than 5 minutes. The bottleneck is often the physical scanning time, not the software processing.

What happens if the software is uncertain about an answer?

Our system detects ambiguities (partially checked box, multiple marks, etc.) and flags them for manual verification. You can view the scanned copy side by side with the detected answers and correct if necessary. This double check guarantees 100% accuracy.

Can I use your AI-generated MCQs with the scanner?

Absolutely! That's even the recommended use. Generate your MCQs with our AI, print them with the automatically integrated recognition markers, distribute them to your students, then scan the copies. The system automatically recognizes the structure and corrects in seconds.

Does scanning comply with GDPR and data privacy?

Yes, fully. All scanned copies and personal data are encrypted and stored on secure servers in France/EU. You remain the owner of your data and can delete it at any time. See our privacy policy for more details.
