Don't think so. At our centre, days when there're lots of students taking the subject, like chemistry,bio,phys,math,etc., we sit by seating plan. Other times, in subjects like Accounting which few ppl take, we sit randomly with the hall divided up amongst the subjects. Sumtimes it's by skool on the latter days. It depends on ur invigilators I guess. But about the paper, as long as it's got ur centre number and candidate number on it, it shld be ok. The invigilators wld have told u if it was necessary to sit by seating plan...
