The Biology programme for the second year has changed considerably compared to previous years. Did you start your Bachelor's programme in or previous to 2017-2018, and have you not yet finished all the compulsory second year courses (i.e. Semester 1-courses in the second year)? For all theoretical courses that are no longer offered, there will be a final resit ("bezemtentamen") scheduled in 2019-2020. If you did not pass one of the practical courses, or have other questions about the transition from the old to the new programme, please contact your student advisor.
