Hello Divakar,

Since you failed to upload the documents on the date mentioned to you, your documents won't be accepted by the website as you already crossed the given date. In such situation , the registration process is not completed and the candidate do nit become eligible to answer the CET exam.

If you still want to know what else can you do, the only option is to contact the authorities through the official website of KCET and mail them or call them explaining your issue and maybe they can help you.

Good luck and stay safe!
