In course week 18 your supervisor shall send a notification to the course manager if you are ready to present your project or not.
There will be at least three opportunities to present your project each year, so it is not a big problem if you are not finished in time for the first presentation opportunity. It is more important that you make a project and write a report that you are proud of. The degree project is the final thing that you make in your studies, and it shall reflect all the knowledge you gain in your years of studying.
