when i have to take the principal signature on CET application form,i mean at the time of verification or after applying for CET exam.
The signature of principal on CET application form is required during the time of verification.Once the entire process of registration is done,you need to take out the print of the application form to fill it up.In application form you need to do your signature and affix your photograph and your left thumb impression.After doing all this you need to get signature of your principal on the application form.
