Yes, you can get admission to a government college with a duplicate TC. Since you lost your original TC, you can apply for a duplicate one by contacting your previous school/college. Make sure to give the correct information and documents if needed.

Hello Manish,

You don't need to take tension. You'll need to approach the school and give a written request asking for a duplicate copy of the TC to be issued to you. Please mention that you lost the TC and immediately require it for seeking admission in college. Mention relevant details in the application. Like your full name, class you studied in, father's name, contact number. You'll get your new TC in few days. All the best!
