The opposite of being off the mark is being accurate, precise, or on target. When someone is off the mark, they are not hitting their intended goals or objectives, but rather falling short of them. To be accurate means to accomplish what you set out to do and to achieve your desired outcome. To be precise is to be exact and specific in your actions or language, leaving no room for error or confusion. Finally, something or someone that is on target is meeting their goals and objectives in a satisfactory manner. By being on target, they are achieving success and making progress toward their goals.
