✅ Common Causes and Fixes
| What Might Be Wrong | What You Can Do |
|---|---|
| Low lighting in the room | Sit in a well-lit room, preferably with natural light or a lamp facing you. Avoid backlighting. |
| Dirty or smudged webcam lens | Gently clean the webcam lens with a soft cloth before starting the test. |
| Webcam resolution is set too low | Close all apps using your camera, then restart the test. |
| Using a low-end or external webcam | Use your built-in laptop webcam if possible — they usually offer better quality for proctoring. |
| Background is too dark | Sit against a neutral-colored wall in a well-lit space to avoid contrast issues. |
| Internet speed is unstable | Graininess may appear if video is compressed. Run a speed test and ensure stable connection. |
