Time flies. I came to Germany 11 months ago and I studied German at two different language schools for about 9 months before I took the German Goethe Certificate B2 Exam in June.
I did not have a chance to take the German B1 exam, so I cannot compare it with the B2. At the moment, I am about to start preparing for the Goethe-Zertifikat C1 Exam and I can surely see the difference between B2 and C1 levels. A friend of mine who took B1 Exam and saw my B2 level books mentioned that B2 looks more complicated. At the same time, a fellow student was encouraging me, saying that B2 exam is easy, because a friend of his took it earlier and passed excellently. The truth is: B2 exam is tricky, because even though the entire exam sets are supposed to be the same level of difficulty, they are not. Not from a foreigner’s point of view. I noticed that while preparing for the test. Books that help you to prepare for the exam and have sets of exercises consist of many texts. Very often, one text is much easier than another. It all depends on your vocabulary. It just happens that some sets of the exam are easier/ more difficult than the others, just because of the tasks vocabulary. My advice is do not underestimate the difficulty of the exam. If a friend of yours claimed he/she passed the exam without studying much, he/she might have got lucky. Take into consideration that a friend of yours might study the language longer than you or has more possibilities to practice his/her language skills and so on.
I would like to talk briefly about the exam, give my pieces of advice on what to review before the exam and share my personal score on the exam.
