“Know your exam desk”  :-  Students will be always in hurry/tension when they are about to attend exams and if you provide exact location on where they sit and write the exams like floor, room no, desk no, availability (like pen, water etc) etc, it will be very helpful for students. Since it avoids students searching for their exam hall at the exam location. Send notice board highlighting the location or design app where admin can upload students exam location
