Nahi Shayad se kuch pharak nahi padega aise muze lagta, kyoki o just reference ke liye rehta, agar konse paper Mai problem aya to tum us sir se confirm kar sakte .. I think it's OK if not name & sign of invigilator
Sitting arrangement last moment mein @ 1.50 pm change ho gaya tha..So they shifted me in another class room and that invigilator didn't come again to sign my admit card .But my attendance has recorded and answer sheet has properly checked and signed by invilgator.
