| * `demo` receives a `subject` string as an argument and logs out the phrase 'Today we are learning about {subject}' where subject is the param passed in. | ||
| * `grade` receives a `student` object and a `subject` string as arguments and logs out '{student.name} receives a perfect score on {subject}' | ||
