Degree students at other Aalto Schools do not need to separately apply for a study right in order to complete courses at the School of Chemical Engineering.
From the pool of enrolled students, participants for the course are chosen according to a prioritizing order defined for the course. If there is such a prioritizing order defined for the course, it is explained in the course description. Before enrolling for the course, check the preliminary requirements at WebOodi.
