B1 level means that you are able to put into practice the knowledge you have acquired so far. At this level you can understand more complex, abstract, or concrete written and spoken content. You can also communicate with a native speaker without too much difficulty and express yourself in detail on a relatively wide range of subjects.
This level involves understanding the main information when standard language is used, but also when it comes to familiar matters in everyday areas such as work, school, or leisure. Also, once you have mastered this level, you will be able to cope with most situations you encounter when travelling. You are able to express yourself easily and coherently on familiar topics and areas of personal interest. You can recount experiences and events, state your wishes and goals, and even give brief explanations on these topics.
When it comes to reading, B1 involves understanding simple texts, written in a plain manner. You can understand letters, emails, or books that relate events, wishes, and plans, describe travel and everyday experience. Writing skills at B1 level involve writing intelligible texts using standard language and dealing with familiar topics. If you have reached this language level, writing short accounts of events, experiences or impressions should not pose any problems either. Acquiring B1 level can ensure, for example, that you can sustain a friendship through letters with a native speaker who shares your interests.
