@futurebird A botany professor of mine told us of his first oral exam at university, for which he had prepared exclusively with books. His examiner gave him an A but afterwards asked, whether he had attended any of his lectures, as he had mispronounced the word phloem (sth like Flow-éhm) as "Flöm" (one syllable, with the German letter ö, which can be written as oe, if your keyboard doesn't have an "ö") throughout the exam.
