You can make an appointment for a meeting with the study adviser via https://et.planner.utwente.nl/. These meetings generally take roughly 30 minutes. Sometimes it makes sense to make follow-up appointments. If you have short questions, you can also visit the open office hours on Tuesday, from 12.30 to 13.30. You can also send (short) questions to the study adviser by e-mail: email@example.com.
