Kindly mention English-taught courses from the Electives Area II - Core Electives (other modules) section which you might've found easy in the past or you have cleared with a good grade.
What is easy and what not actually depends on your knowledge and interests. Also the style of the exam influences your grade, some people are more into written ones, others more into oral ones. Shortly summarized, follow your interests. Therefore I can just recommend to read the modulhandbook and see which lectures you like.
