first try to learn how to write out line. out line shows true picture of an essay in css exam. examiner does not usually read ur full essay line by line. as our faculty of csp's told us that after reading outline, examiner decides unconsciously wether candidate is energetic to go over 40 or have to say on 40 or less. so first practice on out line, get them check, then go for essay's body.

Best regards ..
