At TalTech some exams take place already in the middle of Semester. Do not be surprised, when the Lecturer asks you to register to the exam in OIS.
Registration steps in OIS2:
My Study Information >Registration> Assessment of Learning outcome> there is automatically generated list of courses you have registered to, but you are able to search for other exams by name, code, lecturer.
If you do not find your exam date today, may-be it is not added to the system yet - ask from the lecturer.
Good luck!
