Preliminaries
What should you gain out of your B.Sc. Project?1. Learn the METHODOLOGY of doing a project
Plan a work schedule & achieve it Being original Defy obstacles on your own Document your work Work in a team
2. Apply the information you study from different courses in one common project.
3. What kind of ENGINEER are you really going to turn out to be?
