Hello, you said that A 1, A2, B 1 and B2 are European language grading standards. At present, in China, mainly the Goethe Institute has this course (more standardized than the remedial classes outside) and exams. There is no place for exams in Guangzhou. The nearest places to you are Shanghai, Nanjing and Chongqing. You can take the exam whether you are in his class or not, and you can take A2 directly without A/kloc-0. If you can take an examination of Calderon, of course, the certificate of A 1 is unnecessary ~ Telford 16 is roughly equivalent to B2, and 18 is equivalent to C 1~ If you apply for studying abroad, you don't need a language certificate from the school, because it is too low, you usually need at least a certificate of Daf 16, so
