China's exam has nothing to do with the DELF series.
If you want to study abroad, you can prepare TEF and TCF from China. It's not difficult. It's basically no problem to prepare B 1 by heart.
You can apply for the exam time on the pastel system at any time and take the exam at any time. There is no limit to the number of times per year, and the single cost is 1400 RMB (with the trend of price increase).
The form of the exam is decided by drawing lots on the spot, in other words, both exams should be prepared. TEF questions are relatively easy, but if they are wrong, they will be deducted; The topic of TCF is a bit difficult, but if it is wrong, it won't be deducted, and you can get it. Relatively speaking, TCF is easier, but it also varies from person to person.
Now let's talk about the DELF series of exams. Is it Dipl? I study French? Short for aise, you mean DALF is Dipl? Do I want to use French? Short for aise. The examination forms and methods are basically similar. It is equivalent to the Chinese proficiency test in China, and it is one of the important documents for applying for French schools. B 1 or above is required for undergraduate courses, and C 1 or above is generally required for graduate students. A 1，A2，B 1，B2，C 1，C2 * *。
The content of the exam depends on different levels, basically including listening comprehension, oral expression, reading comprehension and written expression. Because it is written expression and oral test, the content of the test is more comprehensive and more difficult than TEF and TCF series tests.
DELF exam is divided into DELF tous publics and DELF scolaire, which is relatively easy for students to choose.
Finally, it is not clear whether TEF and TCF will expire. However, the DELF series is valid indefinitely.
