Further Notes About Assessment Methods

A midterm exam about the theoretical lessons will be done in the 14.week. A project will be prepared in the content of laboratory practices. This project will include the application of coating and laminating recipes suitable for different areas of coating and lamination. The findings of coating and laminating practices will be presented in the 12.week. The project will be evaluated and taken as the midterm exam. The results of midterm and project will determine the midterm grade. 40% of midterm grade and 60% of final exam will determine the final grade.
