Immunology is a very interesting and clinically relevant subject that introduces you to how the immune system works. It is definitely worth learning the material properly, as many topics will come up again in other subjects and clinical courses. 

The course consists of 10 online lectures, 5 in-person classes and 5 seminars. After each seminar there is  a short online test and during the classes a lot of questions will be asked, so it is important to keep up with the material throughout the semester rather than leaving everything until the credits.

There are two credits during the semester. The professor usually provides Powerpoint presentations and if you keep up with the material regularly, the credits should be quite manageable. 

It is also worth talking to students from previous years and asking them for any study materials or tips they found useful.
