In a case study, a researcher looks at how a group, person, or situation has changed over a certain period of time. Finishing a case study smoothly is challenging because the information must be original and authentic. Inexperienced students face difficulty in a case study because it requires a lot of research, analysis, and a good way to organize data. Students have to do a lot of work during their study time in school. Some of these tasks can be very time-consuming. Assignments take time, awareness, skills, and potential to complete.
