Hello,

You can use a scanner if you have one at your house or you can visit nearest internet cafe and get it scanned using a scanner. You can get it sent to your email ID or copy the file in a pen drive. You have to upload full document , in case if it is half document then your application might not be accepted. Alternatively, you may use scanner in mobile, there are various apps such as Adobe scanner which you can install and just take the photo of the class 10th certificate make a PDF file and upload it in the application form. You will be able to capture full image regardless of the size of the certificate.  The file size must be in between 50-300 KB.
