Well, in the BEC exam, your seats are arranged alphabetically by your name, so in fact, you can only infer that you may have the same surname as you. .
The oral exam is arranged from the first one down, two by two. There are many objective factors, for example, someone may miss the exam, and he may think that he forgot the oral exam after taking the written exam, so your other half is the person in front of you or behind you, if he doesn't leave. In this way, if there are odd numbers left in the end, three people will take the last game together.
In terms of skills, you'd better get familiar with your partner first. We had lunch and went back to the classroom to wait. Then the teacher read the name and went down. At this time, two partners in a group sit together and get familiar with each other. You can practice any topic in the oral test book, then find the tacit understanding and decide who will speak first, and then (the dialogue part). Of course, if your partner is easy to talk to, you can still talk.
In a word, I can't stop you from being nervous. I am nervous before the exam, during the exam, and after the exam. I won't say if you are nervous.
I wish you success!
