Students who copy common textbook problems orreproduce topics from websites such as Khan

Academy or Numberphile usually do not score well.Try to do in-depth research and come up with your

own topics

Students inserted the mathematical modelobtained from the calculator without much

explanation. For example, modelling of musicalnotes is one of the more popular IAs. Students justplotted the function without much explanation on
