There are many things in life that requires precision. In certain jobs being precise is very important. For example an eye surgeon operating someone's eye. Being precise and accurate is also required of your school work.
To be precise and accurate means a requirement to constantly check your work and evaluate the contents for improvement. To reiterate the process until further effort to improve the work is no longer worth it. When you finish your homework, that is not the end. In fact, finishing your homework should be the beginning of the checking phase. To ensure you have the best possible answer within the time you are given.
Some students asked me: "Cher, what is Wendy's?" Well, if I drew MacDonald s, that would be too common. Wendy's is a pretty new fast food chain in Singapore.
Anyway, hope the cartoons will always be a good reminder for you to CHECK your work. =)
