• Hi.                                                                                 If you are private candidate then you don't have to sign with principal you can get signed with your exam centre supp on exam day if you go before exam it is good for you so there is no headache for you on exam day

Hi Aspirant

You can go to your school principal to get his/her signature.Usually most of the students prefer their school principal for this as they were studying in that school.If you want to get it signed by some other person center superviser/incharge then you  might face lots of problem .So it would be the best to go the school principal .

Hope this helps you.
