Is principal's signature neededd here?

So this is nse admit card form, I've applied for nsea nsec and I'm a dummy school student who has to go to school for 3 days but I can't go there because of my institute mock test on the school days. So can y'all tell me whether i should go and get the seal and signature of principal from school or should i let it be and put the rest of my information and the invigilators will let me peacefully give the exam?
