Frequently Asked Questions (FAQ)

Are all 20 to 300 question OMR PDFs true vector A4 files?

Yes. Every PDF in this table is generated mathematically at exact ISO 216 A4 coordinates (210 × 297 mm / 595.28 × 841.89 pt) using pure black vector lines on a white background. Match the question count and answer options to your practice paper.

Can I customize any row in this table with my coaching institute name or watermark?

Yes! Click the "Customize" button on any row to open that exact layout in our in-browser generator, where you can add your institute name, subject, watermark text, instructions panel, and signature boxes. Match the question count and answer options to your practice paper.

What can and cannot be done with the corner alignment marks and camera grader?

All sheets include 4 solid black corner alignment squares designed for our local in-browser Beta Camera Grader. However, camera grading is a beta utility that depends on lighting, camera angle, and 100% print scale—we make no 100% accuracy claims, and these sheets are not programmed for proprietary commercial hardware OMR scanners.
