Reduce file size for online uploads with these tips:

1. Scan only what is necessary (the barcoded cover page and the completed answer sheet). Do not scan in the question paper.
   
2. Adjust your scanner settings: scan in greyscale and set the scanner to 300 DPI (dots per inch). A higher DPI will significantly increase the file size.
   
3. If you are using a smartphone application to scan, make sure to adjust the app’s settings prior to scanning a learner’s cover page and answer sheet: set the app to scan in greyscale and reduce the file size when exporting it to your computer/laptop.

CamScanner is an accessible and free-to-use smartphone scanning application. Please refer to the detailed instructions for reducing file size when using the CamScanner smartphone app, available on the Optimi Learning Portal under Resources > (Academic Year) > Test and Exams.
