If you are looking for CATTI, you can sign up for the professional exam. They are also responsible for examinations and training. As for other translation exams, they are everywhere. There are also some in New Oriental, but generally it is not the CATTI outside, but other translation exams, like the one outside. I recommend you to take the CATTI exam. This is a certificate issued by the Foreign Languages Department. That's awesome. I wish you success!
