Principal's signature in examination form

I am a student of PCC and my PCC examination is due on June, 2009. I have purchased the institute examination form and the supplementary for as well. In the supplementary form there is a section where principal's signature alongwith his/her membership no. is required to certify that the articled assistant has served the prescribed period of articleship. But my principal is not in India at present and will be back in middle of april. At this circumstances can any other partner in my firm sign the form on behalf of my principal.

At this circumstances your valuable suggestion will be very precious to me.
