Prepare fully. "What to read and what to leave" is a wrong attitude. Do not leave or set aside the question asked in the previous papers. Take care of small things, like your pen, pencil, and ink/refill. Your ink must be brilliant and you must have an extra pen. Your writing must be clear and legible. A bad handwriting annoys the examiner. Keep your watch well set and in order. Take care of your handkerchief, spectacles etc. Every small thing has its own importance. Take care of everything; God is always willing and keen to grant you success. Only you must be sure how keen you yourself are!!
