Hello 

Hall ticket is a very important document and one must be very careful in handling it as without it you can't give your exam.CET hall ticket if was given to you online then you can download the same but in case you got it from the university then you must contact them and ask them to provide you with a new one due to the reason that you have lots it .

Thank you
