This may sound stupid , but is it like golf where your card must be 100% correct (I don't play golf so that may be wrong lol)

No-one has ever looked at mine too closely. You will probably get it wrong the first few times so don't worry if that happens. Just write something down after every move and you should be fine. You don't need to bother recording moves once your clock is under 5 minutes, which is useful to know.
