Hi,

You didn't mentioned exactly about which CET you are taking about. If it will be clear it  will easy to help you out.

However, whenever any institution conducts the entrance exam, for students help there is always a helpline number or email id. So you should go to the official Website of the CET entrance exam and find out the helpline number or email id from there. On this you can ask them for your help or queries.

Hope you find this helpful.
