We are very happy to welcome you to spend a semester or year studying with us in the Faculty of Science. Here you will find information on your course schedules and course and exam enrolment.


You can find information on your schedule by looking under the different study programme tabs on the student website: Schedules. Note that you need to select the relevant study programme from the dark grey bar to view the corresponding information on the programme tab.

Course and exam enrolment

All courses taken at Leiden University for credit must be registered in uSis. You can all relevant find information on the students website: Course and exam enrolment.

Please note that if you're new to Leiden, you don't need to register for courses beforehand. During the facultary introduction meeting during the OWL Orientation week, the faculty staff will give you an explanation about how to enroll for your courses and exams in uSis. After these instructions, students need to register their pre-approved Science courses in uSis themselves. We recommend students to search for the courses in uSis by class numbers.

If you have any questions, please do not hesitate to contact:
