5 EC can be obtained for participation in a full Summer/Winter School, e.i. attending two courses in week 1 and two courses in week 2 (3 EC for attending the courses; 2 EC for the paper). You will need to participate: read the materials and attend the lectures. There are no exams nor other ways in which the student is evaluated. However, you should extend the credit to 5 EC by writing a paper as a sequel to one of the courses. The exact requirements you need to negociate with the LOT instructor (note that the lecturer should be affiliated with a Dutch university).
